benchexcal - Benchmark, Expand, and Calibrate (BenchExCal) Trial Emulation Tools

Lightweight tools for evaluating real-world evidence (RWE) studies that emulate randomized clinical trials (RCTs). Provides (1) computation of the three pre-specified RCT-DUPLICATE / ENCORE agreement metrics -- statistical significance agreement (SA), estimate agreement (EA), and standardized difference agreement (SD) -- and (2) the Benchmark, Expand, and Calibrate (BenchExCal) calibration of a Stage 2 RWE study using the divergence observed in a Stage 1 RCT-RWE pair, plus tipping-point sensitivity analysis and forest plots. Methods follow Wang et al. JAMA 2023;329:1376 and Wang et al. CPT 2025;117:1820.
