Flow diagram of the study selection. 456 articles were identified from Medline and EMBASE and further 11 relevant articles were identified through reference lists of highly selective studies. After filtering the duplicates, 360 articles were excluded since they were not related to our topic. 46 full-text articles were assessed for eligibility. Meta-analyses, observational studies, and letters to editor were further eliminated (n = 26). Studies including data for patients with ITDM which were unable to be retrieved were also eliminated (n = 10). Finally 6 RCTs involving 10 studies were selected for this systematic review and meta-analysis
