“…Given that generalized anxiety disorder was reported across 184 studies, we were able to further interrogate the prevalence of this disorder across important subgroups (Figure 3). While investigating generalized anxiety by country income status, we found a higher prevalence among studies performed in lower-middle-income countries (27.6%; 95% CI, 21.6%-33.9%; 59 studies 27, 29-32, 60, 76, 119-121, 129-146, 168, 174-193, 195-197, 209, 211-214, 228, 229 ; n = 25 109) compared with low-income countries (24.0%; 95% CI, 15.3%-33.8%; 11 studies 28, [122][123][124][125][126][127][128]169,199,227 ; n = 4961). Upper-middleincome countries had the lowest prevalence (19.1%; 95% CI, 16.0%-22.4%; 110 studies 33-57, 59, 61-75, 77-97, 99-113, 116-118, 147-155, 159-165, 167, 198, 201, 203-205, 217-224, 226 ; n = 138 496).…”
