Obstetric and newborn characteristics according to randomization to neonatal or infant PCV7 schedule or to control group.

Continuous variables are expressed as mean with standard deviation. Missing data resulted in varying denominators for the following variables: age mother, neonatal, n = 100; infant, n = 103; control, n = 108; smoking pregnancy, neonatal, n = 95; infant, n = 93; control, n = 102; tetanus vaccination, neonatal, n = 89; infant, n = 87; control, n = 94; foetal distress, neonatal, n = 89; infant, n = 85; control, n = 94; delivery, neonatal, n = 100; infant, n = 98; control, n = 107; gestational age, neonatal, n = 103; infant, n = 101; control, n = 102; birth weight, neonatal, n = 103; infant, n = 101; control, n = 102; birth length, neonatal, n = 98; infant, n = 97; control, n = 98; head circumference, neonatal, n = 102; infant, n = 94; control, n = 97; maternal haemoglobin, neonatal, n = 91; infant, n = 87; control, n = 83.
