Risk of readmission for women with a pregnancy complicated by HDP compared with women without HDP
| Outcome | Unadjusted OR (95% CI) | P value | Covariate adjusted OR (95% CI) | P value |
| CV readmission | 2.59 (2.39 to 2.81) | <0.001 | 2.41 (2.08 to 2.80) | <0.001 |
| Non-CV readmission | 1.36 (1.34 to 1.38) | <0.001 | 1.11 (1.09 to 1.14) | <0.001 |
| Any readmission | 1.39 (1.37 to 1.41) | <0.001 | 1.13 (1.10 to 1.15) | <0.001 |
