Surgical apgar score predicts early complication in transfemoral amputees: Retrospective study of 170 major amputations

Table 5 Logistic regression analysis of surgical APGAR score groups and complications/death

Score	SAS 9-10	SAS 7-8	SAS 5-6	SAS 0-4
All patients (%)	5 (3)	57 (34)	70 (41)	38 (22)
Complications and deaths within SAS group (%)	1 (20)	14 (25)	29 (41)	22 (58)
Odds Ratio between groups (reference SAS 9-10)	(ref.)	OR = 1.30 CI: 0.13-12.64 P = 0.82	OR = 2.83 CI: 0.30-26.64 P = 0.36	OR = 5.50 CI: 0.56-53.99 P = 0.143
Linearity of the model, OR (95%CI), P-value	2.00 (CI: 1.33-3.03) P = 0.001
Transfemoral procedure, n = 100 (%)	4 (4)	31 (31)	38 (38)	27 (27)
Complications and deaths within SAS group (%)	1 (25)	8 (26)	17 (45)	20 (74)
Odds ratio between groups (reference SAS 9-10)	(ref.)	OR = 1.04 CI: 0.10-11.52 P = 0.97	OR = 2.43 CI: 0.23-25.51 P = 0.46	OR = 8.57 CI: 0.76-96.52 P = 0.08
Linearity of the model, OR (95%CI), P-value	2.61 (CI: 1.52-4.47) P < 0.001
Transtibial procedure, n = 70 (%)	1 (1)	26 (37)	32 (46)	11 (16)
Complications and deaths within SAS group (%)	0 (0)	6 (23)	12 (38)	2 (18)
Odds Ratio between groups (reference SAS 7-8)	1	(ref.)	OR = 0.74 CI: 0.13-4.41 P = 0.74	OR = 2.00 CI: 0.63-6.38 P = 0.24
Linearity of the model, OR (95%CI), P-value	1.12 (CI: 0.55-2.29) P = 0.76

¹Only one TTA in the SAS 9-10 group. SAS 7-8 is therefore used as the reference group. TTA: Transtibial amputation; TFA: Transfemoral amputation.
