Table 1.
Comparison of linear trends of CM among all women at a delivery admission to women with CM who did not have chronic hypertension, preeclampsia, or chronic hypertension with preeclampsia during the years 2000 – 2009 by linear regression (significance defined as P-value < 0.01). See Figure 2 for graphical representation.
| Condition | aSlope | R2 | P-value |
bP-value comparing condition slope to CM |
|---|---|---|---|---|
| All women with Cardiomyopathy (CM) | 0.021 | 0.90 | <0.001 | -- |
| CM among those women without chronic hypertension |
0.009 | 0.55 | 0.015 | 0.005 |
| CM among those women without preeclampsia |
0.015 | 0.80 | <0.001 | 0.120 |
| CM among those women without chronic hypertension and preeclampsia |
0.020 | 0.88 | <0.001 | 0.804 |
a
Slope (Δy/Δx) reported is the change in the listed condition per 1000 deliveries (Δy) per year (Δx) (Figure 2)
b
Comparison of the slope obtained from the linear regression of the trends for CM among all women to the slope obtained from linear regression for women with CM who did not also have chronic hypertension, preeclampsia, or chronic hypertension with preeclampsia.
