Medical Statistics
Enabling medics to perform high level statistics on the fly
Features
Essential calculators and converters with superior accuracy and precision
Confidence Interval Calculators
Calculate confidence intervals for means and proportions to estimate the range within which the true population parameter lies with a given level of certainty.
P-value to CI Converter
Convert p-values to confidence intervals to provide a range of values that reflect the estimate’s precision and stability, enhancing interpretability.
CI to p-value Converter
Convert confidence intervals to p-values to determine the statistical significance and assess the strength of the evidence against the null hypothesis.
I² Confidence Interval Calculator
Calculate confidence intervals for I² in meta-analyses to assess the degree of heterogeneity and variability among different study results.
Prediction Interval Calculator
Calculate prediction intervals for any type of effect in meta-analyses to provide a range where the true effect is expected to fall in similar studies.
Statistical & Epidemiological Vocabulary
200+ statistical and medical terms defined using reputable sources, such as the ISO and Taber's Cyclopedic Medical Dictionary.

Tutorials
We have created some real-life examples of how INTVL could be used when dealing with heterogeneity in meta-analyses.
Example 1
Is asthma really a protective factor against COVID-19 mortality? Odds ratios and moderate I² levels
Example 2
Latest meta-analysis of RCTs: only mRNA COVID-19 vaccines are certain to reduce chances of infection
