Passing-Bablok regression is inappropriate for assessing association between structure and function in glaucoma

摘要

Redmond and colleagues1 wrote a very interesting manuscript where they used Passing–Bablok regression2 (PBR) to test whether or not structural and functional measures are associated in healthy eyes and in eyes with early glaucoma. One of their main conclusions is that even in healthy subjects there is an association between structure and function. This conclusion is in conflict with previous findings.3,4
