However, there was no significant difference in median adherence levels between women and men for these three drug groups, although there was a significantly lower median adherence in women observed for beta blockers in this univariate analysis (Supplementary Table S3). Restricted cubic spline models...
In addition, the restricted cubic splines is one of the most ideal function models used in dose-response analysis, which allows the risk to vary without sudden jump from one interval to the next one16. In this study, we aimed to investigate the continuous ORs of BMI on three common ...
For metals significantly associated with IS risk in the single-metal or multiple-metal model, we further explored the associations using the restricted cubic spline analysis. The reference values (OR = 1) were set at 10th percentiles, and the knots were set at the 20th, 40th, 60th, and...

Rheumatoid arthritis (RA) is a chronic autoimmune disease associated with systemic inflammation and erosive and symmetrical polyarthritis.1 RA is more common in women and is predominantly in middle...
HR for the primary outcome according to the log2-transformed ratio of 12 months to baseline CA125 were modeled using adjusted restricted cubic spline analysis. The referent point is patients with no change in CA125. The dashed lines represent 95% CIs of the HR estimates. A value of 1.0 on...
To account for a non-linear association, we used restricted cubic spline analysis. The U-shaped association found, represented in Figure1, showed a consistent protection against incident depression for baseline moderate alcohol intake. Figure 1 ...

analysis and found that the interaction was not significant (Fig.3). We also conducted a post-hoc subgroup analysis using NT-proBNP as a continuous measure modeled as a restricted cubic spline and found no evidence of a difference in the effect of dapagliflozin by baseline NT-proBNP levels ...
