Dose–response relationship between components of the Mediterranean Diet Score
(MDS-gram; see Table 1 for details) and
relative risk of total prostate cancer (n 2336): (a) MUFA and PUFA to
SFA (MP:S) ratio, (b) vegetables, (c) fruits and nuts, (d) legumes, (e) cereals, (f)
fish, (g) meat and meat products, (h) dairy products and (i) alcohol. Results from
restricted cubic regression splines with five knots. (–––), OR; (-------), 95 % CI.
The CI cross at the reference point, equivalent to the tenth centile of the intake in
the study population. Regression models include age (in 5-year intervals), region of
residence (north/central), education (0–9 years; 10–12 years; ≥13 years), smoking
status (never/former/current), BMI (quartile distribution of controls), energy intake
(quartile distribution of controls), physical activity (quartile distribution of
controls), history of diabetes (yes/no) and family history of prostate cancer
(yes/no).
