Table 2.
a) The risk of late miscarriage and preterm birth, according to GDM status at inclusion in 772/773 women. | ||||||
GDM at inclusion (WHO 1999) | p-value | GDM at inclusion (WHO 2013) | p-value | |||
Yes | No | Yes | No | |||
N (%) | 77 (10) | 695 (90) | 160 (21) | 613 (79) | ||
Late miscarriage | 4 (5.2) | 7 (1.0) | 0.003 | 6 (3.8) | 5 (0.8) | 0.005 |
Preterm birth | 3 (3.9) | 44 (6.3) | 0.40 | 7 (4.4) | 40 (6.5) | 0.31 |
b) Determinants of late miscarriage, logistical regression. | ||||||

Total model (enter) | p = 0.009 |
OR = odds ratio, CI = confidence interval.
*Confidence interval cannot be computed, as none of the women with late miscarriage did smoke (Fisher’s exact test p = 0.65). Multivariable logistical regression using model: Enter.
