I am very happy with the achievement of our team! Our new R package, rnmamod, is finally in The R Foundation @[email protected] and offers a rich, user-friendly visualisation toolkit that aids appraisal and interpretation of (N)MA results while providing submission-ready output.

Authenticity is more than speaking. Authenticity is also about doing. Every decision we make says something about who we are.

A manuscript that offers a useful extension of the modelling framework of fractional polynomials on network meta-analysis with time-to-event data allowing the joint synthesis of observed and censored time-to-event data along with its inherent limitations. journals.sagepub.com/doi/10.1177/26…

"Do things for your own satisfaction. Consider praise from others to be a bonus. If you don't work for their validation in the first place, you won't need it to feel satisfied once it's done." -James Clear

A recently published article addresses key challenges in NMA and highlights how intransitivity is more common than expected and how traditional statistical tests often fail to provide reliable conclusions for transitivity evaluation. bmcmedresmethodol.biomedcentral.com/articles/10.11…
