- W2597665840 abstract "Introduction: Electronic searches of bibliographic databases in search of randomized controlled trials (RCTs) may be thought to yield paradoxical results. On the one hand, it is increasingly known that electronic databases miss a significant number of true RCTs that can be identified by hand searching journals. On the other hand, all citations retrieved from an optimally sensitive search are not necessarily true reports of RCTs. One practical, relevant question is the degree to which individual citations may accura-tely be classified as true RCTs on the basis of the database's abstract alone. Objective: To ascertain the degree to which individual Medline (Index Medicus) Embase (Excerpta Medica) citations may accurately be classified as true RCTs on the basis of the database's abstract alone, or whether a detailed reading of all articles, particularly methods sections, is necessary. Methods: A total of 108 citations were retrieved in electronic searches of Medline Embase databases from 1980-1993, based on the Cochrane Collaboration search strategy for RCTs (1994 Cochrane Collaboration Handbook, Chapter V) in combination with and asthma and education. Each citation was classified on the basis of the abstract alone by two independent raters as (1) a true RCT, (2) not a true RCT, or (3) too ambiguous to classify without additional information. Inter-rater agreement between the two raters was calculated using the Kappa coefficient. The raters then classified each citation into one of the three categories on the basis of the version of the article. A Kappa coefficient was again calculated to estimate inter-rater agreement of classification. Categories 2 3 were then combined a 2 x 2 table was constructed in order to assess the accuracy of RCT classification by alone, using classification as the gold standard for comparative purposes. The sensitivity, specificity, predictive values of abstract classification were then calculated, as well as true false positive negative rates. Results/Discussion: This project is in progress. Results, which will be presented, will permit a direct comparison of estimates of inter-rater agreement in classifying RCTs between using an abstracts only approach versus a more intensive full text approach. Estimates of the accuracy of abstract classification is particularly important if this approach is used to make initial inclusionary/exclusionary judgments of RCTs for systematic reviews." @default.
