When the λ value was 0.0167674, the minimum cross-validation error plus one standard deviation was determined, and twelve clinical variables with non-zero coefficients were obtained (Hb_min, Potassium_max, BUN_max, HR_max, RR_max, SBP_min, SpO2_min, Liver_disease, AKI, Sepsis, CRRT, Vasopressor). Here, GSTM1 is linked to acute kidney injury.
