Table 3 showed the correlation between variables and screening uptake among the respondents. There was a strong correlation between PSA and DRE screening (r = 0.638). There is no correlation between PSA and DRE screening and dietary pattern (r = −0.054 and −0.049, respectively), and as knowledge of PCa increases, the quality of dietary pattern decreases (r =−0.142). The gene discussed is KLK3; the disease is posterior cortical atrophy.
