Relative risks (RRs) and 95% confidence intervals of prostate cancer per interquartile range (IQR) increase in total mono-unsaturated fatty acids (A and B) and total poly-unsaturated fatty acids (C and D) among all cases (A and C) and aggressive tumors (B and D) by increasing follow-up time since blood collection. The relative risks (RRs) were conditioned on the matching variables (smoking status at baseline and length of follow-up). Regression line (dashed line) was obtained by linearly plotting RR of prostate cancer by circulating fatty acids per IQR vs years. CI = confidence interval; MUFA = mono-unsaturated fatty acids; PUFA = poly-unsaturated fatty acids; RR = relative risk.
