Gestational diabetes

Gestational diabetes (RF_GDIAB) has long been associated with a higher probability of pre-term labor (birth before the 37th week, for which GESTREC3 can be used).  Discuss the observed proportions for this example. Interpret the test of whether mothers with gestational diabetes are more likely to have a higher chance of delivery before the 37th week compared with those not having gestational diabetes. Also interpret the odds ratio provided by SAS, as well as the relative risk of a pre-term birth.
