Extends EVPI and EVPPI to multicenter and meta-analysis settings by accounting for between-cluster heterogeneity, with illustration on the ADNEX model showing zero global value of information but nonzero local value.

Proposes and compares CG-C, 2MA-C and MIX-C random-effects approaches for clustered flexible calibration plots, with simulation and case-study evidence favoring 2MA-C (splines) for overall curves and MIX-C for cluster-specific curves.

Clustered Flexible Calibration Plots For Binary Outcomes Using Random Effects Modeling
Proposes and compares CG-C, 2MA-C and MIX-C random-effects approaches for clustered flexible calibration plots, with simulation and case-study evidence favoring 2MA-C (splines) for overall curves and MIX-C for cluster-specific curves.
