Each ranking was cross-checked with a second researcher to improve inter-rater reliability. To analyze evolution of research quality over time, three updated CPGs were randomly selected and compared to their original versions. Chi-square analysis was then performed to determine statistical significance.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"j_jom-2020-0081_abs_004_w2aab3b7c20b1b6b1aab1c16b4Aa\">\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>We evaluated the quality of research for 2,920 recommendations within the 29 CPGs that met our criteria and found that 418 (14%) were developed using high-quality (Level I) research from randomized, controlled trials. Of the remaining recommendations, 928 (32%) were based on moderate quality research (observational studies) and 1574 (54%) on low quality research (expert opinion).
