| Characteristic | Measure | MWNH (1) N = 202 | MWH (2) N = 66 | p value |
|---|---|---|---|---|
| White race (Caucasian) | Percent | 86.1 | 90.9 | n.s. (3) |
| Number of pregnancies | Mean | 2.61 | 3.94 | < 0.001 |
| Number of live births | Mean | 2.61 | 2.52 | n.s. |
| Age at proband's birth | Mean years | 25.27 | 24.91 | n.s. |
| Age at interview | Mean years | 44.22 | 41.31 | n.s. |
Notes: (1) MWNH = mothers with no history of spontaneous abortion. (2) MWH = mothers with history of spontaneous abortion. Cases with stillbirths excluded from the analysis. (3) Fisher exact p value calculated on cell frequencies (not shown).
