Glucose metabolism and prostate cancer risk. a Spearman’s correlation coefficient (Corr.) matrix for lysophosphatidylcholines (LPCs) with glucose values from the oral glucose tolerance test (0 h and 2 h; n = 1493); p values indicated by the size of the black circles and strength of each correlation by the colour intensity (blue scale). b Odds ratio (OR) values for the association between glucose metabolism status at baseline (impaired glucose tolerance (IGT), impaired fasting glucose (IFG) and type 2 diabetes (T2D)) and prostate cancer risk in the different subgroups (left panel). OR (95% CI) for the association between baseline IGT and prostate cancer risk in different subgroups (right panel). OR > 1, red; OR < 1, blue; level of significance indicated by the size of the black circles. Subgroups: overall prostate cancer (40–60 years, 770 matched case-control sets; 40–50 years, 331 sets; 60 years, 439 sets), non-aggressive prostate cancer (40–60 years, 604 sets; 40–50 years, 287 sets; 60 years, 317 sets) and aggressive prostate cancer (40–60 years, 166 sets; 40–50 years, 44 sets; 60 years, 122 sets)
