  1. Abbreviations: SD, standard deviation; BT, body temperature; HR, heart rate; RR, respiratory rate; SBP, systolic blood pressure; DBP, diastolic blood pressure; MAP, mean arterial pressure; LOS, length of stay in hospital.
  2. Continuous variables (age, BT, HR, RR, SBP, DBP, LOS) were represented as mean ± standard deviation (SD), and were tested using independent t-test.
  3. Number (n) and percentage (%) represented categorical data (male gender, suicide attempt, psychiatric medical history), and Chi-square test was used as indicated.
  4. Case fatality means in-hospital mortality.
  5. *The p value is < 0.05 after excluding the patients with paraquat intoxication.
