Available tools
- At Risk Window Entry Gap Tool Calculate at risk window entry gap from explicit caller-supplied inputs.
- Binary Outcome Discordant Pair Flag Tool Classify one supplied paired binary observation without a hypothesis test or outcome interpretation.
- Censored Event Riskset Flag Tool Inspect an explicit at-risk interval with supplied pre/post-exit evaluation policy; event and censoring are distinct flags.
- Clinical Endpoint Adjudication Label Render a recorded endpoint-adjudication state and reviewer code without adjudicating a clinical outcome.
- Cluster Observation Support Share Tool Deduplicate cluster-level weights before measuring any-observation support; repeated cluster weights must agree.
- Cluster Weight Size Ratio Tool Calculate cluster weight size ratio from explicit caller-supplied inputs.
- Competing Event Cause Token Record an explicit competing-event cause code without inferring causal or clinical classification.
- Contribution Person Days Exclusion Offset Subtract explicitly excluded person-days from recorded study exposure, retaining inconsistent negative totals.
- Diagnostic Indeterminate Result Flag Distinguish caller-defined indeterminate test-result codes from missing-result codes without reclassifying either as positive or negative.
- Diagnostic Verification Status Tag Label a supplied study diagnostic-verification status without interpreting test results.
- Endpoint Component Availability Share Tool Audit supplied endpoint availability without imputing a composite clinical outcome.
- Endpoint Observed Adjudicated Pair Preserve explicit observed and adjudicated endpoint codes as distinct fields without reconciling clinical judgments.
- Event Censoring Status Token Encode explicit event-observed and observation-ended flags while distinguishing ongoing follow-up from censoring.
- Exposure Offset Log Term Tool Return one log exposure offset relative to an explicit reference unit, without fitting a count model.
- Follow Up Visit Window Offset Compare an observed follow-up day with an explicitly supplied asymmetric inclusive visit window.
- Matched Set Case Control Count Describe a positive-case matched set’s member count and control/case ratio without evaluating matching quality.
- Pair Matched Discordance Budget Tool Calculate pair matched discordance budget from explicit caller-supplied inputs.
- Paired Binary Discordance Term Tool Compute an explicitly continuity-corrected paired-discordance contribution without a p-value or significance rule.
- Person Time Interval At Risk Intersect one explicit entry/exit interval with a study observation window using half-open time boundaries.
- Person Visit Loss Follow Up Censoring Code Preserve explicit study follow-up censoring metadata without assigning an event time or censoring mechanism.
- Recurrent Event At Risk Gap Calculate signed time from an explicitly supplied recurrent-event risk restart to the next event.
- Risk Set Event Inclusion Check Check entry < event time against an explicit inclusive/exclusive exit convention for one delayed-entry risk-set record.
- Risk Set Left Entry Equality Flag Tool Risk-set membership under explicitly supplied entry and exit equality conventions.
- Study Composite Component Event Tag Associate an explicitly recorded event component with a supplied composite endpoint identifier.
- Study Treatment Policy Exposure Label Record explicit treatment-policy exposure metadata and estimand source without imputing treatment effects.
- Survival Entry Exit Order Flag Report survival-record entry/exit ordering without discarding a negative duration or estimating survival.
- Survival Tie Censor Order Token Tool One supplied tied-time survival factor with explicit censor/event ordering, not a fitted survival curve.
- Trial Cluster Design Effect Input Evaluate the equal-size-cluster design effect 1+(m−1)rho from explicit inputs without accounting for unequal cluster sizes.
- Trial Stratum Zero Event Domain Tool Distinguish a defined zero event rate from an undefined logarithm or zero exposure.
