Summary
Background
The quality of reporting randomized controlled trials (RCTs) in the dermatology literature has not received much consideration since the late 2000s.
Objectives
We aimed to assess the quality of recently reported RCTs published in dermatology journals, focusing on randomization processes, blinding and trial registration.
Methods
We reviewed 2042 original articles and identified 141 primary reports of RCTs in four dermatology journals (Journal of the American Academy of Dermatology, JAMA Dermatology, Journal of Investigative Dermatology and British Journal of Dermatology) from January 2015 to December 2017. Details were extracted from articles, supplements and public trial registries. A multivariable logistic regression analysis was conducted to identify factors associated with optimal reporting quality.
Results
Among the 141 RCTs, 99 (70·2%), 82 (58·2%) and 69 (48·9%) described methods used for randomization, allocation concealment and implementation, respectively. Most trials (126, 89·4%) reported blinding status; however, one‐third did not state the similarity of the intervention. Furthermore, 52 RCTs (36·9%) were not registered prospectively. Trials published in the British Journal of Dermatology and using central randomization were significantly associated with optimal reporting quality after adjusting for covariates.
Conclusions
Several critical items in reporting RCTs, including allocation concealment, similarity of interventions in blinded trials and prospective trial registration, have remained unsatisfactory in the recent dermatology literature.
Long-pulsed Nd : YAG laser can be considered as another effective and safe treatment modality for stubborn telangeictasia even on face, if applied cautiously.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
