Network meta analysis- Ifplot command

[Elen Xr]

Hello,

Does anyone know how to use the command ifplot in stata for network meta analysis? Which ES , SE we use? And for the direct and indirect comparisons??

Thank you

Hello! I'd say the same used for "metan". For example:

metan _y _stderr, label (namevar=trial_name) by (_contrast) randomi nooverall sortby (trial_code) eform
ifplot _y _stderr _t1 _t2 trial_code, eform

It estimates loop inconsistency (if the outcome is binary and you use the "eform" option, it estimates the ratio of odds ratios between direct and indirect effects, using the higher as numerator, because direction doesn't matter) and loop heterogeneity (assuming it is common within each loop).
