Recommendations for reporting statistical results when comparing proportions

This article serves as the first in a series that will offer recommendations for optimal data reporting, specifically focusing on statistical methods most frequently reported by the Cytopathology audience. Recommendations for reporting statistical results when comparing proportions is the first topic in the series since comparing proportions, particularly utilising the chi-square test, was the most commonly reported inferential statistical test category over 2.5 years of Cytopathology articles.(1) While this article will provide a summary of common tests used to compare proportions, an extensive review of each method, including test assumptions and calculations, is beyond the scope of this summary. The author recommends consulting a trained statistician prior to data collection to discuss an analytical plan, including determining the appropriate statistical test(s) to use.
