Consumption of sugared coffee and sugar-free coffee showed a similar relationship with prostate cancer risk, the point-estimated HRs being close.
LVEF modified the outcomes associated with diabetes, with HRs being 1.29 (1.19–1.40) and 1.61 (1.49–1.74) in patients with LVEF <40% and LVEF ≥40%, respectively (P = 0.03).
Socioeconomic differences in survival were partly explained by cancer stage and less by comorbidity or smoking (stage- and comorbidty- adjusted HRs being 1.07; 0.96–1.19 for education and 1.15; 0.86–1.52 for income).
The study showed that the more peripheral the work position an individual held, the higher his or her risk of DP was with especially high HRs being found among younger individuals.
The relative excess was even more pronounced for renal failure, with HRs being 17-fold, 18-fold, and 5-fold greater in groups A, B, and C, respectively, compared with individuals without diabetes.
This approach could lead to potential bias towards the null hypothesis of no difference, because Figures 3 and 4 show a possible trend with the most significant HRs being the ones with the shortest follow-up time.
