Results After controlling for potential confounders, an increase mean score from 48.22 61.67 decreased by −2.95 (95% CI: 0.06, 0.53; p trend = 0.005). inversely associated levels NO those highest scores compared lowest after adjustment confounders (β −7.69; 95% −14.68, −0.69; 0.028). hPDI 47.96 65.25 −11.92 −19.74, −4.10; 0.003). Conclusion Our findings suggest that higher adherence style, as evidenced values, significantly lower NO.
