Evaluation of multimorbidity and multimorbidity networks.
| Group | Network density | Average degree | Average degree of CVD-H-Hb | CCI | ||||
|---|---|---|---|---|---|---|---|---|
| CVD | non-CVD | Z | P-value | |||||
| Total | — | 0.305 | 5.80 | 29.33 (10, 19, 15) | 3.80 ± 1.62 | 1.19 ± 1.34 | 72.26 | <0.001 |
| Sex | Male | 0.170 | 3.74 | 24.67 (8, 14, 15) | 3.71 ± 1.54 | 1.20 ± 1.31 | 45.41 | <0.001 |
| Female | 0.296 | 6.52 | 32.00 (14, 21, 13) | 3.86 ± 1.66 | 1.18 ± 1.38 | 55.82 | <0.001 | |
| Agea | Young | 0.065 | 1.36 | 8.00 (0, 8, 4) | 1.72 ± 1.03 | 0.29 ± 0.56 | 21.99 | <0.001 |
| Middle-age | 0.303 | 6.36 | 32.00 (11, 21, 16) | 3.52 ± 1.44 | 1.48 ± 1.24 | 55.15 | <0.001 | |

aThe people with age less than 40 (age ≤ 40) were viewed as young, and people with 41 ≤ age ≤ 65 and age ≥ 66were middle-age and old, respectively.
bCVD-H-H refers to the “CVD-Hyperlipidemia-Hypertension” triangle in the network, and the values in the brackets are degrees of CVD, hyperlipidemia and hypertension.
