Multivariable Logistic Regression For Very Low Adherence

Predictor	Fully adjusted* odds ratios (95% CI)	Weight for clinical prediction rule
Prior non-adherence	9.42 (1.37 – 64.75)	9
Agree that side effects are concerning	2.51 (0.99 – 6.37)	3
Agree that taking too many different medications	1.72 (0.75 – 3.95)	2
Disagree that osteoporosis is a worry	3.30 (1.28 – 8.50)	3
Disagree that a broken bone will cause disability	2.51 (0.96 – 6.55)	3
Disagree that medications will help you stay active	2.17 (0.92 – 5.11)	2
Drink ≥ 2 drinks per day on 3+ days per week	8.85 (1.71 – 45.84)	9

Very low adherence refers to a medication possession ratio < 20%. The variable selection is described in text. The fully adjusted odds ratios come from a model adjusted for all predictors noted above. The weights for the clinical prediction rule are proportional to the odds ratios and the total possible score for the clinical prediction rule = 31.
