A 2016 meta-analysis of 43 studies involving 27,905 people in more than 26 countries conflates many of these findings into pooled odds ratios linking suboptimal adherence to virologic failure. (23) While 15 studies took place in North America, 14 occurred in sub-Saharan Africa, 6 in Europe or Australia, 5 in Asia, and 3 in several countries.
Virologic failure rates were estimated for patients within categorized levels of adherence and logistic regression was used to estimate the overall relationship between virologic failure and varying levels of adherence.

Occasionally, transient low-level viremia (ie, a viral blip) is detected by viral load assays, often causing anxiety on the part of patients and clinicians about pending virologic failure or the emergence of drug resistance The occurrence of viral blips may lead clinicians to order costly and unnecessary tests and alter medication regimens of otherwise well-controlled patients.
