Table 4 Odds ratios and 95% confidence intervals for sarcopenia, by tertile of dietary pattern 1 scores

	Dietary Pattern 1 scores			p for trend
	Tertile 1 (low)	Tertile 2	Tertile 3 (high)	p for trend
Subjects with/without sarcopenia	63/472	63/473	43/492
Model 1^a	1.00 (reference)	0.83 (0.55–1.25)	0.56 (0.35–0.88)	0.012
Model 2^b	1.00 (reference)	0.88 (0.56–1.37)	0.57 (0.34–0.94)	0.022
