  • Announcing improved table1_mc: Stata module to create "Table 1.docx" of baseline characteristics for a manuscript

    Dear Statalisters,

    I have just posted an updated version of my program table1_mc on SSC. To make use of the ability to put the output into a docx file, version 15.1 is required, otherwise version 14.2.

    . sysuse auto, clear
    . generate much_headroom = (headroom>3)
    . table1_mc, by(foreign) vars(price conts \ weight contn %5.0f \ rep78 cate \ much_headroom bin) nospace clear
    . table1_mc_dta2docx using "C:\example Table 1.docx", replace tablenumber("Table 1.") tabletitle("Car characteristics by car type.") footnote("Foreign cars included Audi, Datsun, Toyota and VW cars.")

    Congratulations, really awesome!

    I have just two questions:

    First, I wonder whether it is possible to add a * sign to p-values, crossed with, say, the information about the respective test on the footnote, such as p = 0.07* and in the foootnote: * = Pearson chi-square; ** Mann-Whitney, etc.

    Second, I know we may add the total and get, say, the mean value for the total sample, but I wonder whether we could get a column with the "available" cases according to each variable.

    Thank you for this program.
    Best regards,

    Marcos

      Hi Marcos

      I'm glad you like the program!

      The following option is probably best to use to say what test was used.
      test include column describing the significance test used

      As for adding available cases, here's the beginnings of how you could do that:
      sysuse auto, clear
      table1_mc, by(foreign) vars(price conts \ weight contn %5.0f \ rep78 cate) extraspace clear total(before)
      browse
      rename N_T AvailableCases
      drop *T
      table1_mc_dta2docx using "C:\example Table 1.docx", replace

      Cheers,
      Mark

        Thank you for the tips, Mark. I’m on a trip and, as soon as I come back to ‘my Stata’, I’ll add the options you suggested.

        Again, congratulations for such a helpful program.
        Best regards,

        Marcos

          Mark Chatfield : I wonder whether it is possible to abridge a specific command.

          For example: instead of typing each variable name, then selecting for each one whether it is, say, "countn", than formating for each one the decimals, is there some way we could select a given specification for a row of variables, as we do when using, say, var1-var50 in "regular" Stata.

          I tried with - vars(var1-var100 countn %5.1f), to no avail.

          Considering I'd have to type 50 variables plus the selected test plust the format for decimals, it would give quite a big line for the command.

          Thanks in advance.
          Best regards,

          Marcos

            Hi Marcos

            Not easy for me to do that, but easy for you to do that:

            . foreach v of var var1-var100 {
            . local vlist "`vlist' `v' contn %5.1f "
            . }
            . table1_mc, vars(`vlist')

            ps There is the format option to set the default for formatting continuous variables which you might like to use.

            Cheers,
            Mark

              Hi Mark Chatfield , thank you for the reply and the command. Perhaps there is something missing. I tried it with the example below, and I still keep getting just the first variable:

              Code:
              . sysuse auto
              (1978 Automobile Data)
              
              . foreach v of var price-displacement {
                2. local vlist "`vlist' `v' contn %5.1f "
                3. }
              
              . table1_mc, by(foreign) vars(`vlist')

                |          N=52        N=22                |
                |------------------------------------------|
                | Price    6072.4 ()   6384.7 ()    0.68   |
                +------------------------------------------+
              Data are presented as mean (SD).
              I wonder whether some extra fiddling with the code could solve the problem.

              Thanks in advance.

                Hi Marcos

                It just needs the backslash (\) added

                . local vlist "`vlist' `v' contn %5.1f "

                . display "`vlist'"
                would have revealed this.

                Cheers,
                Mark

                  Sorry, the backslash after %5.1f and before " gets deleted whenever I save

                    Mark Chatfield: Thank you for the helpful command. The added backlash provided the desired output:

                    However, for a reason I cannot envisage, the .docx file gets an error.

                    We get the results of "make" variable" (and I didn't ask for that in the command), the firts two lines are in bold, and we don't get the results by "foreign", according to the command I typed.

                    Please see below.

                    The output in Word is like this:

                      Mark Chatfield : I tried to use table1_mc_dta2docx in another computer (also Windows 10), and I got the same odd display. I wonder whether this is a bug or I’m missing something.

                      Thanks in advance.

                        Hi Marcos, if you would like to email me directly (my email address can be found on http://researchers.uq.edu.au/researcher/20374), I can look into this if you haven't solved it yet. Please provide me with all the Stata syntax you used.

                          Hi all
                          I've uploaded a newer version of table1_mc. Along with one bug fix (N and m now reported correctly when row -rather than the default column- percentages), I've expanded the Remarks section to mention Susan Donath's new -baselinetable- command (Stata Journal 18-2), and a command -tabxml- for use in surveys:

                          Remarks

                          table1_mc is an extension and modification of Phil Clayton's table1 command.

                          Other user written commands that do similar things include:
                          baselinetable ... very nice, but no p-values. Can use any statistics from summarise, can't report geometric
                          mean and geometric SD.
                          tabout ... http://tabout.net.au/docs/home.php
                          sumtable ... two stats in two (not one) columns, generally not as flexible, no p-values
                          partchart ... quite similar but strangely doesn't seem to express IQR as (Q1-Q3), reporting instead the
                          difference between the two quartiles
                          tabxml ... survey data frequencies and/or % for categorical variables, means and SE / CI for continuous
                          variables. To avoid matsum error message: . net install sg100, from(http://www.stata.com/stb/stb47)

                          See also
                          http://blog.stata.com/2017/04/06/cre...ts-for-arbitrary-variables/

                          While table1_mc does not report an effect size (e.g. differences in means, medians or proportions) &
                          associated 95% CI for a variable when there are 2 or more groups, readers might consider calculating and
                          reporting these also.
