Adjusted measures of association between supplement use and medication use in Old Order Amish study participants from Lancaster County in whom dietary supplement and medication use was assessed in a cross-sectional study.

Odds Ratio 95% CI P
Number of any supplement 0.96 0.92 to 1.00 0.047
Number of vitamins/minerals 0.99 0.90 to 1.09 0.8
Number of herbal supplements 0.94 0.89 to 0.99 0.025
