ITC & NMA

Indirect treatment comparison and network meta-analysis.

When you don't have a head-to-head trial, ITCs and NMAs estimate relative effects across a network of trials connected by a common comparator.

glossaryITCNMA

Indirect treatment comparisons (ITCs) estimate relative effects between treatments that were never compared head-to-head, by linking them through a common comparator. A network meta-analysis (NMA) generalises this across a connected network of trials. Where networks don't connect, an anchored or unanchored MAIC can adjust for population differences using individual patient data.

Reviewers care about: assumption of consistency, transitivity, choice of effect modifiers, and whether you've pre-registered the analysis. Unanchored MAICs face the highest scrutiny.
