Abstract

Objective:

To evaluate and compare the reporting of consolidated standard of reporting trial (CONSORT) flow diagrams in randomized controlled trials (RCTs) published in a national and international pharmacology journal.

Methods:

RCTs in an international pharmacology journal, European Journal of Clinical Pharmacology (EJCP), and a national journal, Indian Journal of Pharmacology (IJP), published from January 2014 to July 2016 were evaluated for reporting and completeness of CONSORT flow diagrams. A total of 138 articles (EJCP = 90; IJP = 48) were analyzed and compared.

Results:

Of 138 RCTs analyzed, 90 were from EJCP and 48 were from IJP. 76.6% (69/90) articles from EJCP and 37.5% (18/48) articles from IJP had reported the CONSORT flow diagram. Of these, 95.5% (66/69) had assessed for eligibility in EJCP and 88.8% (16/18) had reported the same in IJP. The number of participants excluded was reported in 86.9% (60/69) flow diagrams in EJCP and 83.3% (15/18) in IJP. 82.6% (57/69) flow diagrams in EJCP and 77.7% (14/18) in IJP had mentioned the details of randomization. Allocation of intervention was reported in 91.3% (63/69) flow diagrams in EJCP and 88.8% (16/18) in IJP. 60.8% (42/69) flow diagrams in EJCP and 44.4% (08/18) in IJP had mentioned the details of follow-up of participants. 95.5% (66/69) flow diagrams in EJCP and 94.4% (17/18) in IJP had mentioned details about analysis.

Conclusion:

In spite of both the journals, IJP and EJCP endorsing the CONSORT statement, a significant difference in the reporting of CONSORT flow diagrams in RCTs can be noted. The quality of reporting can be improved by stringent publication guidelines by the editors.
