Cox proportional hazards regression for the association between sex- and age group-specific tertiles for grip strength (GS) measures (reference group: strong tertile) with mortality (n = 4,143) and cerebrovascular event (n = 3,309).
| Mortality | Cerebrovascular event | |
|---|---|---|
| Exposure | HR (95% CI) | HR (95% CI) |
| GS | ||
| Weak | 1.83 (1.51, 2.22) | 1.12 (0.86, 1.47) |
| Moderate-strength | 1.42 (1.16, 1.73) | 1.12 (0.87, 1.44) |
| NGSmass | ||
| Weak | 1.46 (1.21, 1.76) | 1.54 (1.19, 2.01) |
| Moderate-strength | 1.03 (0.84, 1.26) | 1.06 (0.81, 1.40) |
| NGSBMI | ||
| Weak | 1.50 (1.24, 1.82) | 1.37 (1.06, 1.79) |
| Moderate-strength | 1.07 (0.87, 1.31) | 1.05 (0.80, 1.37) |
| GS1-2 | ||
| Weak | 1.20 (0.99, 1.46) | 1.11 (0.85, 1.44) |
| Moderate-strength | 1.14 (0.94, 1.38) | 1.03 (0.79, 1.34) |
HR, hazard ratio; CI, confidence interval; NGS, normalized grip strength; NGSmass, absolute grip strength divided by body mass; NGSBMI, absolute grip strength divided by body mass index; GS1-2, percent change of grip strength from round 1 to round 2. Significant HRs are bolded.
