Non-operative management for penetrating splenic trauma: how far can we go to save splenic function?

Table 1 Comparison of baseline characteristics

Gender (M/F)	42/3	47/4	20/2
SBP (mmHg)	117 (94–137)^a	129 (115–141)^a ^,Φ	117 (105–124)^Φ
Pulse rate (bpm)	103 (82–124)^a	89 (74–108)^a	98 (83–106)
GCS	15 (14–15)^†	15 (15–15)^†	15 (15–15)
Serum Hb (g/dL)	11 (9.2–12.7)	11.5 (9.7–13.4)	11.8 (10–12.8)
Thrombocytes count (×10⁹/L)	212 (124–290)^a ^,‡	274 (208–319)^a	281 (208–391)^‡
