However, their findings were not consistent between men and women. Independent of sample size, diabetes was not associated with green tea and total caffeine intake in men. Combining the results from men and women, especially considering the significant sex-based difference in the rate of response to the 5-year follow-up questionnaire (44.3% vs. 52.1%), probably made the study's conclusions inaccurate. It may be worth investigating differences in body mass index (BMI) and other important factors between respondents ...References1. Iso H, Date C, Wakai K, Fukui M, Tamakoshi A.
