Rigora Statistics Tools are a set of browser-based calculators developed for medical researchers. Built by a publishing physician-scientist, the tools handle specific statistical tasks that appear in research papers while keeping all data inside the user's browser.
The collection consists of four named calculators. The baseline characteristics Table 1 generator accepts a dataset upload and produces a publication-ready table that applies the appropriate summary statistics to each variable; output options include Word, PDF, and R code. The sample size and power calculator determines required sample size or achieved power for comparisons of two means or two proportions and supplies a methods sentence together with R code. The diagnostic test calculator converts a 2×2 table into sensitivity, specificity, predictive values, and likelihood ratios, each accompanied by a 95 percent confidence interval and R code. The odds ratio and relative risk calculator transforms a 2×2 table into odds ratio, relative risk, absolute risk difference, and number needed to treat, again with 95 percent confidence intervals and R code.
All tools are free, delivered entirely through the browser, and export both formatted text suitable for manuscripts and corresponding R code. They address the repetitive calculations and formatting required for tables and statistical reporting in medical papers. When more extensive analysis is needed, the same provider offers a separate paid statistics service led by a physician-scientist.
In the Productivity & Work space, Rigora Statistics Tools takes a focused approach. Manually creating publication-ready statistical tables, calculating sample sizes, and deriving diagnostic metrics with confidence intervals for research papers. It is built as a consumer product for medical researchers and physician-scientists. Rigora Statistics Tools is free to use. It runs on the web.
Behind Rigora Statistics Tools is Rigora Scientific Editing, and it first shipped in 2024. Among its 6 catalogued features are Baseline Table Generator, Sample Size Calculator, and Diagnostic Test Calculator. The interface is available in 4 languages, including German, English, and Spanish.
