  • metalong now available on SSC: longitudinal meta-analysis with sensitivity diagnostics

    Dear Statalist members,

    I am pleased to share that metaLong is now available on the SSC archive:

    ssc install metalong

    metaLong provides a workflow for longitudinal meta-analysis, where studies report outcomes at multiple follow-up time points. The package integrates:

    - Random-effects pooling with cluster-robust variance estimation
    - Time-varying sensitivity analysis using ITCV
    - Benchmark calibration against observed covariates
    - Leave-k-out fragility analysis
    - Restricted cubic spline trends over time
    - Automated publication-ready figures

    The commands are designed to handle dependent effect sizes across time and to provide integrated robustness diagnostics within a single pipeline.

    A simple example:

    sim_longmeta, k(20) times(0 6 12 24) seed(42) clear
    ml_meta yi vi, study(study) time(time) saving(meta_res) replace
    ml_sens yi vi, study(study) time(time) ///
    metafile(meta_res) saving(sens_res) replace
    ml_benchmark yi vi, study(study) time(time) ///
    metafile(meta_res) sensfile(sens_res) ///
    covariates(pub_year quality n) saving(bench_res) replace
    ml_fragility yi vi, study(study) time(time) ///
    metafile(meta_res) saving(frag_res) replace
    ml_spline, metafile(meta_res) df(3) saving(spline_res) replace
    metalong_plot, metafile(meta_res) sensfile(sens_res) ///
    splinefile(spline_res) fragfile(frag_res) ///
    saving(figure.gph) replace
