Categories of maternal and infant serum 25(OH)D status by visit and group.
| Variables | Visit | 6000 IU Group [n/N (%)] | 600 IU Group [n/N (%)] | p-value |
|---|---|---|---|---|
| Maternal Serum 25(OH)D ≥ 50 nmol/L |
1 | 17/94 (18%) | 15/94 (16%) | 0.70 |
| 4 | 64/68 (94%) | 30/60 (50%) | <0.0001 * | |
| 7 | 54/56 (96%) | 25/48 (52%) | <0.0001 * | |
| Infant Serum 25(OH)D ≥ 50 nmol/L |
1 | 18/93 (19%) | 15/94 (16%) | 0.54 |
| 4 | 59/67 (88%) | 53/60 (88%) | 0.96 | |
| 7 | 49/55 (89%) | 43/47 (91%) | 0.75 |
n = number of observations with serum 25(OH)D value ≥ 50 nmol/L within the group and N is number of observations in each group. (%) is the percentage of serum 25(OH)D ≥ 50 nmol/L within each group. * Significant difference between the two groups of mothers at visits 4 and 7 (Chi-squared test).
