Table 3 Comparison of physiological variables of patients who underwent laparotomy vs. those who underwent non-operative management

From: Management of liver trauma in urban university hospitals in India: an observational multicentre cohort study

Variables OM (n = 106) NOM (n = 263) p value
Age 28 (12.8) 25 (12.6) p = 0.07 t test
Penetrating injury (%) 22 (20.8) 9 (3.5) p < 0.05 t test
SBP (mmHg), mean (SD) 99 (26.6) 111 (21.0) p < 0.05 t test
Heart rate (beats per minute), mean (SD) 103 (20.4) 97 (18.5) p < 0.05 t test
GCS, mean (SD) 13 (3.9) 14 (3.1) p = 0.14 t test
ISS, median (IQR) 14 (9-22) 17 (12-22) p < 0.05 (Wilcoxon’s rank-sum test)
Mortality, n (%) 35 (33.0%) 26 (9.9%) p < 0.05 chi-square
  1. SBP systolic blood pressure, GCS Glasgow Coma Scale, OM operative management (laparotomy), NOM non-operative management, ISS injury severity score
