OBJECTIVE: To assess whether there was an improvement in the quality and quantity of randomized controlled trials (RCTs) in nationally published journals through an application of standardized and validated scores. METHODS: We selected, electronically, for the period of 2000-2009, all RCTs published at the two indexed, orthopaedics-focused Brazilian journals: Acta Ortopédica Brasileira(AOB) and Revista Brasileira de Ortopedia (RBO). These RCTs were identified and scored by two independent researchers according to the JADAD scale and Cochrane Bone, Joint and Muscle Trauma Group score. The selected studies were grouped: 1) by publication period (2000-2004 and 2004-2009); 2) journal of publication (AOB and RBO). RESULTS: Twenty-two papers were selected, 10 from AOB and 12 from RBO. No statistically significant differences were found between the proportion (nRCT/nTotal of published papers) of RCTs published in the two journals (p=0.458), as well as for the JADAD score (p=0.722) and Cochrane score (p=0.630). CONCLUSION: The quality and quantity of randomized clinical trials in the period was similar in the journals analyzed. There is a trend of improvement of quality, yet there was no increase in the number of randomized clinical trials in both periods.
