#Types of randomization trial

Non Randomized: Despite filtering the database to show only randomized clinical trials, further investigation within individual clinical trial webpages and study protocol revealed statements that the trial does not use any randomization procedures. N/A: Despite being listed as a randomized clinical trial, the study protocol listed n/a as their allocation type. No Randomization Protocol: No randomization protocol could be found in the study protocol.

41 is maintained by the National Library of Medicine (NLM) at the National Institutes of Classification is a Web-based resource that provides patients, their family members, health care professionals, researchers, and the public with easy access to information on publicly and privately supported clinical studies on a wide range of diseases and conditions. Selection criteriaĪ review was conducted of all study protocols listed for stage 3 RCTs in of June 1, 2020. The objective of this study was to systematically identify and review Stage 3 RCT protocol guidelines to classify the randomization methods used in order to determine the overall quality of randomization methods used for Stage 3 RCTs in the U.S. Proper randomization is required to generate unbiased comparison groups in controlled trials, yet the majority of study protocols for RCTs currently in // Objectives

More than three quarters of all study protocols (77.7 %) provided incomplete descriptions of the type of randomization. Only 20.8 % of the study protocols described randomization methods. What is the quality of descriptions of randomization methods in the study protocols for phase 3 randomized control trials (RCT)?
