Comparison of 28-day mortality rate and survival time in sepsis patients across different lactate, albumin, and lactate/albumin ratio levels.

Group	Number of cases	28-day mortality rate [% (cases)]	χ²/Z value (mortality)	P value (mortality)	Survival time [d, M (QL, QU)]	χ²/Z value (survival)	P value (survival)
L/A ≤ 0.17 group	231	20.3 (47)	78.890	<.001	27.5 (20.3, 28.0)	116.029	<.001
L/A > 0.17 group	70	82.9 (58)			0.9 (0.9, 2.9)
Albumin ≤23.11 g/L group	52	63.5 (33)	24.084	<.001	3.6 (0.9, 24.3)	47.097	<.001
Albumin >23.11 g/L group	249	27.7 (69)			27.5 (2.7, 28.0)
Lactate >4.22 mmol/L group	87	69.0 (60)	73.340	<.001	0.9 (0.9, 3.6)	110.602	<.001
Lactate ≤4.22 mmol/L	214	20.5 (44)			27.5 (21.2, 28.0)
