Table 3. Multivariate logistic regression analysis: association between adherence variables and failure.

Variable	Univariate OR(95% CI)	Mulitvariate OR (95% CI)*
Cumulative adherence of <95%	2.09 (0.93–4.70)	1.69 (0.71–4.02)
Cumulative adherence of <90%	4.50 (1.31–15.48)	3.01 (0.81–11.21)
One episode of adherence variation of >10%	2.07 (1.01–4.24)	2.20 (1.04–4.64)
≥1 episodes of treatment interruption (≥28 days)	4.42 (1.67–11.70)	4.01 (1.45–11.10)
≥1 episodes of treatment interruption (≥28 days) not due to toxicity	5.62 (1.76–17.97)	3.90 (1.09–13.92)
≥1 episodes of patient initiated treatment interruption (≥28 days)	7.32 (1.30–41.14)	4.40 (0.78–24.93)
