Serum UCH‐L1 levels on hospital admission (Day 1 postpoisoning) in patients with and without cognitive impairment on Day 30 postpoisoning. Serum UCH‐L1 levels on admission were significantly higher in patients with cognitive impairment [8.51 (6.53‐10.22) ng/mL; n = 36] compared to those without [4.25 (2.57‐6.31) ng/mL; n = 171] (P < 0.001). Black horizontal lines indicate the mean, and error bars indicate standard errors. Statistical analysis was performed using the Mann‐Whitney U test
