Complication rates after direct anterior vs posterior approach for hip hemiarthroplasty in elderly individuals with femoral neck fractures

Table 3 Thirty-day mortality rates

	Anterior approach	Posterior approach
ASA 1 + ASA 2 (%)	0/33 (0)	5/68 (6.8)
ASA 3 + ASA 4	4/72 (5.3)	12/86 (12.2)
Log-linear model: Including approach, ASA score, and Death; Chi2 = 12.93-P = 0.039, indicating statistically significant differences from the fitted model, showing that the model did not fit the observed data
The interaction: Approach × Death: P = 0.06
The interaction: ASA score × Death: P = 0.028
