Abstract
INTRODUCTION Antihypertension, intensive glucose control (IGC), and lipid lowering were the main therapeutic strategies in diabetes mellitus. However, the comparative effects of them on renoprotection remain unclear. MATERIALS AND METHODS We searched the PubMed, EMBase, and Cochrane Library up to May 18, 2017, for studies with comparative interventions on regression, end-stage renal disease and all-cause death in diabetes mellitus. Statistical analysis was done using the Bayesian network meta-analysis (NMA). The surface under the cumulative ranking area and median rank were calculated to rank the interventions. RESULTS A total of 73 randomized controlled trials with 13 3703 participants were included for the comparisons of 14 interventions. Angiotensin-converting enzyme inhibitor plus angiotensin receptor blocker (ACEI-ARB) ranked first in regression (odds ratio, 62; 95% confidence interval, 5.2 to > 999); ACEI-ARB also ranked first in end-stage renal disease decline (odds ratio, 0.58, 95% confidence interval, 0.39 - 0.85), followed by IGC hemoglobin A1c less than 6.5% (odds ratio, 0.58, 95% confidence interval, 0.36 - 0.90). The ACEI plus calcium channel blocker reduced all-cause death leaving other interventions insignificant (odds ratio, < 0.001; 95% confidence interval, < 0.001 to 0.30). ). The surface under the cumulative ranking area analyses also matched the result ranks. CONCLUSIONS Compared with antihypertension interventions, IGC including IGC hemoglobin A1c less than 6.5% and lipid lowering, ACEI-ARB showed the best renoprotective effects.
