Issues relating to confounding and meta-analysis when including non-randomized studies in systematic reviews on the effects of interventions.
BACKGROUND Confounding caused by selection bias is often a key difference between non-randomized studies (NRS) and randomized controlled trials (RCTs) of interventions. KEY METHODOLOGICAL ISSUES In this third paper of the series, we consider issues relating to the inclusion of NRS in systematic reviews on the effects of interventions. We discuss whether potential biases from confounding in NR...

Non-randomized studies may provide valuable evidence on the effects of interventions. They are the main source of evidence on the intended effects of some types of interventions and often provide the only evidence about the effects of interventions on long-term outcomes, rare events or adverse effects.

Adherence to the CONSORT Statement in the Reporting of Randomized Controlled Trials on Pharmacological Interventions Published in Iranian Medical Journals
Background: Among manuscripts submitted to biomedical journals, randomized controlled trials (RCTs) form the backbone of evidence-based medicine. Hence, their protocol should be designed rigorously and their results should be reported clearly. To improve the quality of RCT reporting, researchers developed the CONSORT Statement in 1996 and updated it in 2010. This study was designed to assess th...
