Table 4 As-treated Analysis for Transcutaneous Hb at 4 months, Neonatal Jaundice and Polycythemia

From: Effects of timing of umbilical cord clamping on preventing early infancy anemia in low-risk Japanese term infants with planned breastfeeding: a randomized controlled trial

  DCC ECC Relative risk (95% CI) / Mean difference (95% CI) p value
Primary outcome
Spectrophotometric hemoglobin (SpHb) at 4 months
  (n = 137/DCC = 72, ECC = 65) 12.4 (0.8) 12.3 (0.7) 0.1 [−0.18, 0.32] 0.59
Secondary outcome
Anemia (SpHb < 11.0 g/dl) (n = 137/DCC = 72, ECC = 65) 1 (1.4) 0 (0) 1.0 [0.96, 1.01] 1.00
Neonatal jaundice
  Total serum bilirubin (TsB) (days 3-5) a (n = 132/DCC = 70, ECC = 62) 12.9 (3.4) 12.0 (3.5) 0.9 [−0.33, 2.08] 0.15
  Over the excess level of transcutaneous bilirubin (TsB) b (n = 132/DCC = 70, ECC = 62) 7 (10.0) 4 (6.5) 1.6 [0.48, 5.04] 0.54
  Phototherapy c (n = 133/DCC = 70, ECC = 63) 8 (11.4) 4 (6.3) 1.8 [0.57, 5.69] 0.38
Hematocrit
  Hematocrit level (days 3-5) (%) a (n = 131/DCC = 69, ECC = 62) 57.0 (5.1) 52.4 (5.2) 4.6 [2.84, 6.41] < 0.01*
  High hematocrit (Hct65%) (n = 131/DCC = 69, ECC = 62) 3 (4.3) 2 (3.2) 0.7 [0.12, 4.54] 1.00
  1. Data are presented as mean (SD) or n (%)
  2. a The highest value among blood sampling conducted during days 3-5 were used
  3. b Over the excess value are based on Standard of Imura (1985)
  4. c Two (DCC = 1, ECC = 1) received phototherapy before met to standard of phototherapy for preventively. One (ECC = 1) did not received phototherapy even over level of the standard of phototherapy
  5. *p < .05
