Table 2 Subgroup analyses for early compared to delayed cord clamping and odds ratios (OR) of delayed cord clamping (≥ 60 s) among subgroups

From: Factors associated with timing of umbilical cord clamping in tertiary hospital of Nepal

Subgroup Early cord clamping
% (n/N)
Delayed cord clamping
% (n/N)
OR (95% CI)a
Labor/delivery characteristics
 Delivered in labor room (high-risk) 51 (34/67) 41 (25/61) 0.67 (0.33–1.35)
 Night shift 3 (2/67) 15 (9/61) 5.62 (1.38–38.0)
 AMTSL used 97 (65/67) 93 (57/61) 0.44 (0.06–2.33)
 Length of third stage > 7 min 19 (13/67) 18 (11/61) 0.91 (0.37–2.23)
 Maternal blood loss > 100 mLb 6 (4/66) 16 (10/61) 3.04 (0.95–11.6)
 Obstetric complication during delivery 25 (17/67) 46 (28/61) 2.50 (1.19–5.34)
Infant characteristics
 Preterm birthc 7 (5/67) 12 (7/59) 1.67 (0.50–5.93)
 Apgar score < 7 at 1 min 61 (41/67) 51 (31/61) 0.66 (0.32–1.32)
 Any intervention to the infant 27 (18/67) 11 (7/61) 0.35 (0.13–0.88)
  1. Labor/delivery complications included breech presentation, fetal distress, premature rupture of membranes, meconium staining, and various degrees of tears and lacerations
  2. Interventions given to the infant included oxygen administration, penguin/bulb suction, electric suction, bag and mask ventilation, vigorous stimulation, and transfer to the Postnatal Baby Unit
  3. Active Management of Third Stage of Labor (AMTSL) = Uterotonic administration + CCT + Uterine massage
  4. n number of cases where characteristic is yes, N sample size
  5. aCrude odds ratio from univariate logistic regression model
  6. bThis variable excludes one case where maternal blood loss not recorded (remaining n = 127)
  7. cThis variable includes two missing values where gestational age was not available
