  • Propensity score matching- creating tables of matched cohorts

    Hi, I am still at very basic beginner level in Stata, so my apologies if the question sounds silly.

    I have a sample of about 240 patients, out of which around 60 are cases and remaining 180 are controls.

    Using the following command:"teffects psmatch (outcome variable) (treatment dependent var#1 treatment independent Var #1 Var #2), nneighbor(1)", I am able to get the Coef. table for treatments effect estimation.

    However, I am unable to figure out on how to generate a table showing the individual p values of the treatment independent variables after propensity score matching. I know that first part of the table can be generated using the baseline data I have before the PS matching. However, as I said I am unable to find a way to generate the second part of the table ie. after PS matching.

    Baseline characteristics before and after PS matching:
    -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
    .....................................Before PS matching.......................................... ..............After PS matching
    ....................................Cases (n=60) Controls (n=180) p values..........................Cases (n=60) Controls (n=60) p values
    Independent Variable #1
    Independent Variable # 2
    Independent Variable #3
    Independent Variable #4

    Any help is appreciated.

    Thanks

    I don't think teffects psmatch lets you identify which cases matched, so you can't create such tables.

    You might try pstest after psmatch2 . Both programs are part of psmatch2 by Leuven and Sianesi, available from SSC.
