Severity grading scale describing how to evaluate adverse events intensity/severity (grade 1-2-3-4).

The severity grading scale provides harmonised definitions of severity grade 1-2-3-4 for specific conditions as well as recommendation on general grading. It is recommended to use the scale or define a scale when you collect and assess adverse events in your study. This way you ensure data is as harmonised as possible, i.e., a grade 1 anaemia at site A is going to be the same as a grade 1 anaemia at site B. Please note we also have an FAQ document (PV-TB-D21) to further assist doctors with severity grading.
