Background: Clinical guidelines vary in determining optimal blood pressure targets in adults with diabetes mellitus. Methods: We systematically searched PubMed, EMBASE, Cochrane Library, and clinicaltrials.gov in March 2018; conducted random effects frequentist meta-analyses of direct aggregate data; and appraised the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Results: From eligible 14 meta-analyses and 95 publications of randomized controlled trials (RCT), only 6 RCTs directly compared lower versus higher blood pressure targets; remaining RCTs aimed at comparative effectiveness of hypotensive drugs. In adults with diabetes mellitus and elevated systolic blood pressure (SBP), direct evidence (2 RCTs) suggests that intensive target SBP /=90 mmHg, direct evidence (2 RCTs) suggests that intensive DBP target
