Figure 1

Estimated HRs (95%CIs) for the associations of SII level with risk of total and cause-specific mortality. (a) DFTJ cohort; (b) NHANES 1999–2014. DFTJ Dongfeng-tongji, NHANES National Health and Nutrition Examination Survey, SII systemic immune-inflammation index, CVD cardiovascular diseases. Notes: The HRs and 95% CIs were calculated by restricted cubic spline regression models, adjusted for age, sex, race (only in the NHANES 1999–2014), body mass index, smoking status, alcohol drinking status, physical activity status, education and baseline disease histories, with the minimum value of the transformed SII as reference (DFTJ cohort: 6.4; NHANES 1999–2014: 7.0). Knots were placed at the 5th, 50th and 95th percentiles of the SII.
