Overview

A probability nomogram is a visual tool for interpreting how new information changes the probability of a clinical issue such as a diagnosis or risky behavior. It uses Bayes' Theorem to combine the initial probability with the change in likelihood attached to the new assessment finding. The user locates the probability and likelihood on the nomogram and then connects the two points and extends the line to read the updated probability. The nomogram is a fast and free way to estimate updated probabilities without having to do any mental computation, making it more appealing for many practitioners.

Steps to put into practice
