Figure B is a flow chart that summarizes the search and selection of articles related to pressure ulcer risk assessment and prevention strategies. Citations were identified through bibliographic databases, including MEDLINE, CINAHL, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews, as well as through other sources, including experts, reference lists, and grey literature. There were 4,559 abstracts of potentially relevant articles reviewed. After excluding 3,873 abstracts that were not relevant to key questions, and identifying additional hand-searched references, gray literature, and scientific information packets, 686 full-text articles were reviewed for relevance. A total of 579 full-text articles were excluded for the following reasons: wrong population (85), wrong intervention (42), wrong comparator (10), wrong outcome (111), wrong study design for Key Question (185), wrong publication type (121), systematic review (10), and risk factor only (15). In total, 105 studies in 107 pubications were included, with specific details per key question as follows: key question 1, 3 studies; key question 1a, no studies, key question 1b, no studies, key question 2, 47 studies in 48 publications, key question 2a, 19 studies, key question 2b, 6 studies, key question 3, 47 trials in 48 publications, key question 3a, 7 trials, key question 3b, no trials, key question 3c, no trials, key question 4, 13 trials, key question 4a, no trials, key question 4b, no trials, and key question 4c, no trials.
