Methods： Proportions of studies that reported CONSORT and STRICTA items were compared for the years before and after implementation of these two guidelines. In addition, the total score of each item＇s reporting were calculated and reported differences during different date ranges were compared. Results： For CONSORT items （maximum score 8）, there was evidence of a slight improvement in reporting between 1994-1995 and 1999-2000 combined （2.5 ± 0.6） and 2004-2006 and 2009-2010 combined （3.0 ± 0.9; difference 0.4, 95% confidence interval, 0.3 to 0.6, P〈0.01）. For STRICTA items （maximum score 17）, there was evidence that a slight improvement in reporting between 1994-1995 and 1999-2000 combined （8.6±2.1） and 2004-2005 and 2009-2010 combined （10.1 ±1.8; difference 1.5, 95% confidence interval, 1.1 to 1.9, P〈0.01）. Conclusion： Quality of reporting for RCTs of acupuncture treatment conducted in China have generally improved since the introduction of the STRICTA and CONSORT guidelines.展开更多
