Poor reporting of trials does not mean poor quality trials

Poor reporting of methods may not reflect on a trial's quality. Soares and colleagues (p 22) compared the published reports of 56 randomised controlled trials conducted by the Radiation Therapy Oncology Group with the original research protocols. They found that important methods—sample size calculations, concealment of allocation, and intention to treat analysis—were often not mentioned in the final report but had been explicitly stated in the research protocol. The publication of protocols may improve the quality of conducting and reporting clinical research, the authors say, and contacting the trialists may provide additional information when the research is used in meta-analyses.
