Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine (TCM) and results have shown that there is an urgent need for higher quality RCTs on TCM.展开更多

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

Using a sample of non-financial firms listed on the main boards of the Shanghai Stock Exchange and the Shenzhen Stock Exchange between 2006 and 2010, we find that firms are more likely to voluntarily disclose their auditors' reports on internal control if they have higher state ownership, lower managerial ownership, sanction records, audit committees, non-Big Four auditors as their auditors of annual financial reports, unqualified auditors' opinions on financial reports, less board independence, after controlling for firm size, liabilities, performance, and history. Moreover, as compared to a control group that exhibits similar characteristics, firms that voluntarily disclose auditors' reports on internal control are associated with positive earnings quality and negative cost of equity capital.展开更多
