A medical researcher at the University of Warwick, UK, has found the 2,500 year-old Pythagoras theorem could be the most effective way to identify the point at which a patient's health begins to improve.

In a paper published in PLOS ONE, Dr Rob Froud from Warwick Medical School at the University of Warwick worked with his colleague Dr Gary Abel from the University of Cambridge.

They made the discovery after looking at data from ROC (Receiver Operating Characteristic) curves.

These curves were initially developed during World War II for the analysis of signals to help operators decide whether a blip on the screen was an enemy target or allied forces ships or aircrafts.

In the 1980s, the curves were adopted by epidemiologists to help them decide at what point an individual has recovered from an illness.
