%description
Implementation of a novel frequentist approach to produce clinically
relevant treatment hierarchies in network meta-analysis. The method is
based on treatment choice criteria (TCC) and probabilistic ranking models,
as described by Evrenoglou et al. (2024) <DOI:10.48550/arXiv.2406.10612>.
The TCC are defined using a rule based on the minimal clinically important
difference. Using the defined TCC, the study-level data (i.e., treatment
effects and standard errors) are first transformed into a preference
format, indicating either a treatment preference (e.g., treatment A >
treatment B) or a tie (treatment A = treatment B). The preference data are
then synthesized using a probabilistic ranking model, which estimates the
latent ability parameter of each treatment and produces the final
treatment hierarchy. This parameter represents each treatment’s ability to
outperform all the other competing treatments in the network.
Consequently, larger ability estimates indicate higher positions in the
ranking list.
