GA=Gestational age, SBP= systolic blood pressure, DBP= diastolic blood pressure, ALT= alanine transaminase. Values were missing for body-mass index in 5 patients, alanine aminotranferase in 15 patients, serum creatinine in 12 patients, uric acid in 21 patients. P<0.05 is considered signficant.
*
Because the median (25th–75th centile) ranges appear similar despite significant difference in the distribution of creatinine values in the two groups, we report the percentage of creatinine values greater than the median value in each group.
To convert creatinine to mg/dL- divide by 76.26. To convert uric acid to mg/dL- divide by 59.48.
