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