Association between Dietary Inflammatory Index Scores and Diabetes Sensorimotor Polyneuropathy in Patients with Type 2 Diabetes Mellitus: A Case-Control Study

Table 3

Odds ratios (ORs) and 95% confidence intervals (95% CIs) of DSPN according to quartiles of dietary inflammatory index.

	Dietary inflammatory index quartiles				trend
	1 (n = 91) <−0.93	2 (n = 90) (−0.93) − (−0.09)	3 (n = 92) (−0.09) − (1.07)	4 (n = 91) <1.07
	OR	OR (95% CI)	OR (95% CI)	OR (95% CI)
Crude	1.00	0.79 (0.39–1.28)	1.27 (0.71–2.27)	1.76 (1.03–3.36)	0.01
Model 1	1.00	0.79 (0.39–1.27)	1.27 (0.71–2.27)	1.76 (1.03–3.36)	0.01
Model 2	1.00	0.69 (0.37–1.31)	1.21 (0.64–2.26)	2.24 (1.13–4.39)	0.008

Binary logistic regression was used to obtain OR and 95% CI. The overall trend of OR across increasing quartile was examined by considering the median score in each category as a continuous variable. Model 1: adjusted for age (continuous) and sex (male/female). Model 2: further adjustments were made for energy intake (kJ/d or kcal/d), physical activity (low intensity, moderate, or high intensity), education (literate or illiterate), smoking status (yes or no), economic status (low, middle, or high), marital status (married or single), job (working or housewife), BMI (continuous), and WC (continuous).
