A review of mortality from choroidal melanoma. I. Quality of published reports, 1966 through 1988.
The literature concerning mortality after a diagnosis of choroidal melanoma was reviewed to identify relevant articles published from 1966 through 1988 and to select those with mortality rates presented separately by tumor size for inclusion in a pooled analysis (meta-analysis) of 5-year mortality after enucleation for choroidal melanoma. The quality of the published literature for our purposes was assessed. Candidate articles were identified from a search of the MEDLINE files by an information specialist. Altogether, of 217 candidate articles, 76 (70 from the MEDLINE search and six more from our files) qualified for review. All-cause mortality rates were reported in 80% of the articles. Among six aspects of design and methods for which information was sought, eligibility criteria were reported in 52 (68%) of the 76 articles and statistical methods were cited in 38 (50%); other information was reported with intermediate frequency. Quality scores based on completeness of reporting with respect to 16 factors ranged from 13.3 to 92.3 of a possible 100.0. Findings suggest that researchers, clinicians, journal editors, and reviewers should be more attentive to the completeness of reports from clinical research studies with respect to basic information regarding design and methods.
