Highlights1. First MAIC benchmarking of global LAI trials against matched, stratified oral cohorts in Southern China.2. Trial LAI outcomes generally exceeded weighted local oral care rates (10/11 comparisons), alongside trial oral arm benchmarks.3. Outcome differences correlated with cohort demographic overlaps, reflected by effective sample size (ESS).4. Findings favor tailored LAI implementation over universal extrapolation of trial results.
