|Summary of Findings
|Systematic reviews with protocols reported their methods more comprehensively than systematic reviews without protocols, but their median time from search to submission was longer (325 vs. 122 days; P < 0.001) meaning that the searches of systematic reviews with published protocols were about 200 days older compared with their controls. Almost two-thirds of the systematic reviews with protocols and about 10% of the controls could be found in the International Prospective Register of Systematic Reviews (PROSPERO).
