Association of patterns of multimorbidity and number of chronic diseases with mortality

Parameters	Deaths	Mortality (deaths/1000 PYs)	HR (95% CI)
Patterns of multimorbidity
With no multimorbidity	31,854	6.7	1.00
Cardiometabolic multimorbidity	8330	27.3	2.20 (2.14 − 2.26)
Respiratory multimorbidity	656	31.6	2.13 (1.97 − 2.31)
Gastrointestinal and hepatorenal multimorbidity	501	10.9	1.33 (1.22 − 1.46)
Mental and arthritis multimorbidity	67	7.2	1.18 (0.93 − 1.50)
With ≥2 patterns of multimorbidity	309	30.2	2.21 (1.98 − 2.48)
With no specific patterns of multimorbidity	7654	17.4	1.46 (1.42 − 1.50)
Number of chronic diseases
0	11,117	4.1	1.00
1	20,737	10.4	1.59 (1.55 − 1.63)
2	12,284	19.2	2.25 (2.19 − 2.31)
3	3871	25.8	2.69 (2.59 − 2.80)

Any	49,371	8.9	1.36 (1.35 − 1.37)

All models were stratified by age, sex, and area. Multivariable models were adjusted for the same covariates as those in Table 3. CI: Confidence intervals; HR: Hazard ratios; PY: Person year.
