TABLE 2. Risk of perinatal distress and low Apgar score for two subgroups of intrauterine growth-retarded infants (crude and adjusted analysis for birth weight).
|
Risk factor |
Crude analysis |
Adjusted* analysis (by birth weight) |
|
Perinatal distress |
5.6 (2.4-13.0) |
3.2 (1.4-7.5) |
|
Apgar score 5 min <6 |
3.0 (1.3-6.2) |
1.6 (0.7-3.5) |
Rate ratios or odds ratios are calculated comparing the IUGR-low ponderal index group (N=432) with the IUGR-adequate ponderal index group (N=2030). They should be interpreted as increased risk of the low PI-IUGR over the API-IUGR group. No effect: odds ratio = 1.00.
* Logistic regression analysis.
