| Group | n | Tissue inhibitor of metalloproteinase-1 | Positive rate (%) | |||
|---|---|---|---|---|---|---|

| ||||||
| − | + | ++ | +++ | |||
| Normal | 30 | 12 | 10 | 6 | 2 | 60.0 |
| Gestational hypertension | 18 | 7 | 4 | 4 | 3 | 61.1a |
| Mild preeclampsia | 9 | 3 | 3 | 2 | 1 | 66.7b |
| Severe preeclampsia | 16 | 5 | 4 | 3 | 3 | 68.8c |
The χ2 test indicated that there were no statistical differences between every two groups (P>0.05). Statistical differences were not identified between athe gestational hypertension group and controls (P=0.06), bthe mild preeclampsia and gestational hypertension groups (P=0.778) and cthe severe preeclampsia and mild preeclampsia groups (P=0.915).
