One of the most common statistical tests in the medical journals is chi-square test. The present study compares the used chi-square tests in the medical journals with chi-square for trend. The statistical package of EPI6 was used to compare the methods. For some selected papers chi-square test and chi-square test for trend were used. The results showed in some tests although the chi-square test was statistically significant but the chi-square for trend was not significant and vice versus. It can be concluded when analyzing contingency tables, care should be taken for the appropriate test.
