CRP and type 2 diabetes mellitus: Table 1 shows the characteristics of the study population. The percentage of participants with higher 4-PA/PLP (≥0.939) was significantly higher in the LF group than in the non-LF group (62.85% vs. 31.34%). Significant differences were found between age, ethnicity, PIR level, education, physical activity, BMI, energy intake, CRP, SIRI, the history of T2DM, dyslipidemia, hypertension, CVD, and the use of an anti-platelet agent (all p < 0.05).
