For symptomatic disease, the estimate was 9.12% (SD\u00a0=\u00a00.04), with women 9.5% (SD\u00a0=\u00a00.05) and men 6.8% (SD\u00a0=\u00a00.06); prevalence was lowest in North America, 4.6% (SD\u00a0=\u00a00.03) and highest in Africa, 47.9% (SD\u00a0=\u00a01.8). For signs, prevalence was 35.2% (SD\u00a0=\u00a00.3), with woman 34.7% (SD\u00a0=\u00a00.7) and men 37.6% (SD\u00a0=\u00a00.7); North America showed the lowest regional prevalence, 3.5%, (SD\u00a0=\u00a00.4) with Eastern Asia the highest, 42.8% (SD\u00a0=\u00a00.4). Using TFOS DEWS II diagnostic criteria resulted in a global prevalence of 29.5% (SD\u00a0=\u00a00.8), with women 28.1% (SD\u00a0=\u00a01.2) and men 24.9% (SD\u00a0=\u00a01.4). Prevalence was lowest during the fifth decade, increasing approximately linearly with age thereafter.

Estimates can be readily updated as new information emerges, or according to need. Understanding the specific characteristics of studies chosen for inclusion is critical to the validity of the outcome. Although dry eye disease is evidently common, affecting about one in 11 people world\u2010wide, data are sparse for the young and all geographical locations except Eastern Asia.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/opo.12888","type":"journal-article","created":{"date-parts":[[2021,9,21]],"date-time":"2021-09-21T03:40:30Z","timestamp":1632195630000},"page":"1254-1266","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":208,"title":["The global prevalence of dry eye disease: A Bayesian view"],"prefix":"10.1007","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2955-3277","authenticated-orcid":false,"given":"Eric B","family":"Papas","sequence":"first","affiliation":[{"name":"School of Optometry &amp; Vision Science University of New South Wales Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,9,21]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtos.2017.05.008"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtos.2017.05.006"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtos.2018.03.003"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtos.2017.05.003"},{"key":"e_1_2_10_6_1","first-page":"370","article-title":"LII.
