The correlation between serum calcium and PICU mortality remained consistent across different subgroups and was not influenced by factors such as age, gender, serum albumin levels, oxygen saturation and bateremia (P > 0.05). Except for stratification component itself, each stratification factor was adjusted for all other variables (age, sex, WBC, bacteremia, pH, lactate levels, oxygen saturation, serum potassium, serum sodium, blood urea nitrogen, and the use of inotropes).
