Two quality scores were used: a quality index of consumer health information (DISCERN) and the Journal of the American Medical Association (JAMA) benchmark. Readability was evaluated with 3 scores: FleschKincaid Reading Ease (FRE), FleschKincaid Grade (FKG) and Automated Readability Index (ARI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Sites from private hospitals or clinics were the most prevalent in both countries, followed by health platform sites. Final JAMA benchmark was 1.13\u2009\u00b1\u20091.18 in Portugal and 1.07\u2009\u00b1\u20091.00 in Brazil. Final DISCERN was 34.07\u2009\u00b1\u200911.71 in Portugal and 38.17\u2009\u00b1\u200910.51 in Brazil. FRE and FKG scores denoted \u201cdifficult to read\u201d and \u201ccollege school level\u201d in both countries; ARI denoted \u201cprofessor\u201d level in Portugal and \u201ccollege student\u201d level in Brazil needed to understand the text, a statistically significant difference.
