Revisiting the Hunter Gaston discriminatory index: Note of caution and courses of change.

Tuberculosis (Edinburgh, Scotland) - 1 May 2017

Mokrousov Igor

Abstract excerpt

Hunter Gaston Discriminatory Index (HGDI) is a widely used estimator of discriminatory power of genotyping methods and diversity of molecular markers in bacterial pathogens, including Mycobacterium tuberculosis. In my opinion, the index is somewhat misleading: a closer look at common practice and particular studies reveals that values in the range of 0.6-0.9 are modest but uncritically perceived as high. I...
