ORs for the association between risk factors and AKI incidence in meta-regression analyses
| Study level variables | Studies included, n | OR (95% CI) per 10 years or 10% increase | P-value | I 2 (%) | R 2 (%) |
|---|---|---|---|---|---|
| Age (years) | 83 | 2.15 (1.54–3.00) | <0.001 | 96.16 | 22.71 |
| Male (%) | 83 | 1.36 (1.07–1.73) | 0.01 | 96.48 | 7.04 |
| Cardiovascular disease (%) | 64 | 1.53 (1.13–2.08) | 0.01 | 97.14 | 11.48 |
| Diabetes (%) | 72 | 1.48 (1.24–1.77) | <0.001 | 95.85 | 22.87 |
| CKD (%) | 46 | 1.64 (1.40–1.93) | <0.001 | 92.85 | 49.21 |
| Hypertension (%) | 72 | 1.50 (1.33–1.69) | <0.001 | 94.49 | 43.64 |
ORs are interpreted as the OR associated with a 10-year or 10% increase in the prevalence of the risk factor. I2 is the amount of heterogeneity present. R2 is interpreted as the amount of heterogeneity explained by the risk factor.
