Survival Analysis, ROC and Meta-Analysis Tools
Methods for medical, clinical and evidence-synthesis research: time-to-event analysis, diagnostic accuracy, method comparison and pooling results across studies.
Kaplan-Meier Survival Analysis Online
Survival curves with censoring, median survival and the log-rank test between groups.
Replaces SPSS · Prism · StataCox Regression Calculator
Hazard ratios for several predictors of time to event, with confidence intervals.
Replaces SPSS · Stata · SASROC Curve and AUC Calculator
Diagnostic accuracy with the area under the curve, its confidence interval and the optimal cut-off.
Replaces SPSS · MedCalcBland-Altman Plot and Analysis
Agreement between two measurement methods: bias, limits of agreement and proportional bias.
Replaces MedCalc · PrismMeta-Analysis Calculator and Forest Plot
Pool effect sizes with fixed or random effects, heterogeneity (Q, I², τ²) and a forest plot.
Replaces RevMan · CMAKaplan-Meier Survival Analysis Online
Use it for time-to-event data where some cases have not had the event by the end of follow-up (censored), such as time to death, relapse or customer churn.
Cox Regression Calculator
Use it to test several predictors of time to an event at once, such as treatment, age and disease stage.
ROC Curve and AUC Calculator
Use it to judge a diagnostic test or a risk score, and to choose a threshold.
Bland-Altman Plot and Analysis
Use it to compare a new measurement method with an established one. A correlation coefficient is not a measure of agreement.
Meta-Analysis Calculator and Forest Plot
Use it to combine effect sizes (Cohen’s d, Hedges’ g, log odds ratios, correlations as Fisher’s z) from studies of the same question.
