a
All of the variables included in Table 1 were assessed for associations with respiratory distress syndrome and with transient tachypnea of the newborn. Only the variables shown in this table had statistically significant associations with these infant outcomes.
b
Missing data were excluded from all P value calculations.
c
P values are from Fisher exact test.
