# How can menstrual cycle symptoms be measured statistically?

A statistical technique called Trigg's trend analysis can identify symptom patterns throughout the menstrual cycle and measure overall severity mathematically.

 Early or limited evidence

Not applicable (methodological study)

## What they did

Adapted Trigg's trend analysis technique for analyzing prospective symptom ratings to evaluate premenstrual syndrome.

## What they found

The method provides both qualitative and quantitative information about menstrual cycle symptoms. Symptom patterns can be identified using Trigg's tracking signal. A new statistic called the menstrual cycle ratio was proposed as a global index of menstrual cycle morbidity.

## What it means for you

This paper describes a mathematical method for measuring and comparing menstrual cycle symptoms across studies. The main limitation is that this is a methods paper, not a study of women, so it does not tell us how these symptoms affect real life.
