Low quality research can have an error drawing result and it can be distored. Thus, quality assessment is required for appropriate clinical application of the results of studies using randomized controlled trial (RCT).
Materials and Methods:
A quality assessment was conducted on the articles of Prostate published in Republic of Korea, using typical tools of RCT quality analysis such as Jadad scale, van tulder scale, and Cochrane collaboration risk of bias Tool (CCRBT).
The first RCT about Benign prostatic hyperplasia is published in Korean journal of Urology at 1995 and 24 RCTs are publish since then. There were 2 RCTs in 90`s, 10 from 2001 to 2006, 12 from 2007 to 2012 and none in 2013. Five high quality analysis were found in Jadad scale and 8 were in van Tulder scale. Double blinding studies were done in 6 articles, and there was significant difference in quality weather performing double blinding or not.
The number of RCT articles were increased over time. However, quality of RCT articles were vulnerable. In order to develop prostate studies, adequate randomization and blinding methods, IRB review, and financial support are required for the conduct of high quality randomized controlled trials.
