Results: Twenty-one articles(32%) did not report correct p-values, 33 articles(50%) used mean ± standard error(mean ± SE) and 11 articles(l7%) used mean ± standard deviation(mean ± SD). Fifty-two articles(95%) of 55 ones which were tested for normal distribution made an error in describing normal distribution. Seventeen articles misused t-test and 12 articles did not carry out the multiple comparison.
Conclusions: The training of researchers with clinical statistics or the participation of statisticians in research design will reduce the significant errors in statistical interpretation of the results.
