BACKGROUND: For analyzing a repeated ordinal response, it is common to use a multivariate cumulative logit model. This model may fit poorly, especially when a nonsymmetric response is available. In these cases, alternative strategies should be utilized. METHODS: In this paper, we present a family of power transformations for the cumulative probabilities to model asymmetric departures from the random-intercept cumulative logit model. To illustrate this method, we analyze the data from an epidemiologic study to identify risk factors of hypothermia among newly born infants in some referral university hospitals in Tehran, Iran. RESULTS: For hypothermia data, using this family of transformations and comparing the goodness-of-fit statistics showed that a model with the cumulative complementary log-log link gives us a better fit compared to a model with the cumulative logit link. CONCLUSION: In some areas, using the ordinary cumulative logit link function does not lead to the best fit. So, other link functions should be evaluated to discover the best transformation for the cumulative probabilities.
Advances in fetal echocardiography are providing highly accurate diagnoses of congenital heart disease prior to delivery, making it possible to plan the delivery-room management of these newborns. Knowledge of the expected transitional circulation occurring with birth and the pathophysiologic implications of congenital heart disease increases the likelihood of providing efficient and effective therapies. The majority of neonates who have congenital heart disease will not require delivery room resuscitation in excess of routine care; however, a small number of prenatally diagnosed cardiac lesions are more likely to require urgent postnatal intervention immediately following delivery. These cardiac lesions include transposition of the great arteries with intact ventricular septum and restrictive atrial septum, hypoplastic left heart syndrome with intact atrial septum, obstructed total anomalous pulmonary venous return, and complete congenital heart block. Prenatal diagnosis allows for coordination of care surrounding delivery and during the early postnatal hours.
