Methodologies

12 min readWhy statistical correctness needs more than passing software tests

A transparent explanation of why meta-analysis software can run successfully while still producing statistically wrong results, and how review teams should check methods before publication.

16 min readStatistical validation evidence and reproducibility record

How Coventra records numerical validation evidence by comparing app outputs with direct R package results, what the current validation library covers, and what remains a human methodological responsibility.

18 min readMethodology defaults, effect measures, and changeable assumptions

A transparent map of Coventra's default statistical assumptions, which analysis choices users can change, and which assumptions must be verified before journal use.

28 min readPairwise model, effect-size formulas, and heterogeneity

Formula-level documentation for pairwise synthesis, including binary, continuous, generic, and time-to-event data, sparse-data handling, heterogeneity, defaults, and changeable model settings.

14 min readForest plot methodology and display assumptions

How Coventra renders study effects, pooled estimates, weights, confidence intervals, prediction intervals, and journal-style display options.

26 min readSensitivity diagnostics, funnel plots, and small-study effects

Formula-level and interpretation guidance for leave-one-out checks, influence diagnostics, cumulative meta-analysis, funnel plots, Egger, Begg, Peters-style tests, contour guides, and trim-and-fill sensitivity output.

17 min readSubgroup analysis, meta-regression, and moderator interpretation

How subgroup fields and study-level covariates connect to moderator analyses, including formulas, defaults, limitations, and reporting requirements.

20 min readBayesian pairwise meta-analysis, priors, and posterior diagnostics

Coventra's Bayesian pairwise workflow, including exact bayesmeta integration, default priors, changeable prior settings, prior sensitivity, and diagnostic limits.

24 min readNetwork meta-analysis model and relative estimates

Detailed methodology for contrast-based and binary-arm network meta-analysis, including consistency equations, defaults, changeable settings, and transitivity checks.

10 min readNetwork graph methodology

How network plots represent treatments, direct comparisons, multi-arm evidence, and connectivity without implying effect magnitude or certainty.

16 min readP-score rankings, SUCRA-like summaries, and rankograms

How Coventra produces and interprets treatment rankings, including ranking direction, uncertainty, P-scores, and rankogram limitations.

16 min readNMA forest plots, league tables, and heatmaps

Methodology for presenting network estimates versus a reference treatment and all pairwise network comparisons in numeric and heatmap form.

12 min readComparison-adjusted funnel plots for NMA

How comparison-adjusted funnel plots are generated for network meta-analysis and why sparse or heterogeneous networks limit interpretation.

18 min readNetsplit, netheat, contribution, and confidence diagnostics

Network inconsistency and confidence-support outputs, including direct-vs-indirect comparison, loop requirements, contribution matrices, and certainty caveats.

24 min readSingle-arm proportion, rate, and mean meta-analysis

Detailed methodology for pooled single-arm proportions, incidence rates, and raw means, including formulas, GLMM defaults, person-time units, heterogeneity, funnel limitations, and reporting requirements.

18 min readGeneric inverse-variance, hazard ratios, and adjusted estimates

How reported estimates and standard errors are entered, transformed, pooled, and checked when arm-level data are insufficient or inappropriate.

24 min readCluster, crossover, paired, matched, and IPD-derived analyses

Design-specific formulas and extraction requirements for studies that should not be treated as ordinary independent-arm trials.
