TLDR
Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) as discussed by the authors is a set of guidelines for transparent reporting of randomized clinical trials that emphasize the reporting of theories used and descriptions of intervention and comparison conditions, research design, and methods of adjusting for possible biases in evaluation studies that use nonrandomized designs.
Abstract
Developing an evidence base for making public health decisions will require using data from evaluation studies with randomized and nonrandomized designs. Assessing individual studies and using studies in quantitative research syntheses require transparent reporting of the study, with sufficient detail and clarity to readily see differences and similarities among studies in the same area. The Consolidated Standards of Reporting Trials (CONSORT) statement provides guidelines for transparent reporting of randomized clinical trials. We present the initial version of the Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) statement. These guidelines emphasize the reporting of theories used and descriptions of intervention and comparison conditions, research design, and methods of adjusting for possible biases in evaluation studies that use nonrandomized designs.

Evidence-Based Public Health: Moving Beyond Randomized Trials

TL;DR: There is an urgent need to develop evaluation standards and protocols for use in circumstances where RCTs are not appropriate, and both the internal and external validity of RCT findings can be greatly enhanced by observational studies using adequacy or plausibility designs.
