Systematic review on the quality of randomized controlled trials from Saudi Arabia.

ABSTRACT:

Background

The quality of randomized controlled trials from Saudi Arabia is unknown since most are observational studies.

Objective

To determine (1) the quantity and quality of randomized controlled trials published from Saudi Arabia, and (2) whether significance of intervention effect varied by study quality.

Methods

PubMed, SCOPUS, and Cochrane were searched with keywords for trials published from Saudi Arabia until February 2018. A total of 422 records were identified and screened, resulting in 61 eligible trials for analysis. Two researchers abstracted trial characteristics and assessed quality in seven domains (randomization, allocation concealment, blinding of assessors or participants, incomplete outcome data, selective reporting, and other sources of bias) usi
