Evaluation of Randomized Controlled Trials Reports on the Treatment for Tumor in CNKI Database

[Purpose]To assess the quality of randomized controlled trials reports on the treatment for tumor in China. [Methods]All primary reports of randomized controlled trials for tumor treatment published in CNKI from 2006 to 2011 were enrolled. The quality of reporting was assessed according to consolidated standards of reporting trials statement in 2010.[Results]A total of 696 articles which met the inclusion criteria were analyzed. Reports with inclusion and exclusion criteria accounted for 82.04%. Reports describing randomization allocation method,blinding methods,random allocation concealment,baseline data,flow figure,sample size evaluation and trial registration accounted for 14.37%,0.43%,1.15%,1.87%,0.72%,0.29% and 0.14% of all reports respectively. [Conclusion]The quality of randomized controlled trials of cancer treatment is generally low,which needs to be further improved,especially the use of blinding and sample size calculation.
