[HTx Project @HTx_H2020]

This recent HTx study, co-authored by experts at @unibern and @CHEyork (@UniOfYork), describes a cross-network meta-analysis (#NMA)/ network meta-regression (#NMR) model that enables cross-design and cross-format synthesis.

Our paper as one of the top Statistics in Medicine downloaded papers for 2021!
Many thanks again to all co-authors for this nice work and great collaboration! @Geointheworld, @amancayork, Fabio Pellegrini @ESteyerberg & @eggersnsf under @HTx_H2020

@steftsitsipas Not even I experienced that, despite the fact that I was born in 1990 (much earlier before you did).. The mobile phones were discovered much more before you were born (I admit though they were quite popular when I was in school)! So, do you have any personal experience on that?

time to head to the kiosk!

Friday = free IPD meta-analysis advice day.
I call it frIPDay
(yes, really)

#1 examining treatment-covariate interactions in a 1-stage model is dangerous ... simply including an interaction term merges within-trial & across-trial relationships, which may distort results

ROB-MEN tool is now available! Congrats to all for this amazing tool in NMA
