Table I.
Demographic and laboratory observations of the survivors and non-survivors among the 170 patients with acute PQ poisoning.
| Parameter | Survivors (n=93) | Non-survivors (n=77) | P-value |
|---|---|---|---|
| Age (years) | 30.00 (23.00, 45.5) | 29.00 (24.00, 46.50) | 0.518 |
| Time lag after PQ ingestion (h) | 5.00 (4.00, 8.00) | 6.00 (4.00, 8.75) | 0.117 |
| Arterial lactate (mmol/l) | 2.00 (1.00, 2.50) | 5.00 (2.00, 10.00) | <0.001 |
| Arterial lactate-time (mmol/l.h) | 10.00 (5.00, 17.50) | 26.10 (15.00, 53.55) | <0.001 |
| PQ concentration (mg/l) | 5.00 (3.00, 7.00) | 10.00 (6.00, 15.00) | <0.001 |
| PQ concentration-time (mg/l.h) | 26.50 (13.50, 47.50) | 59.00 (35.50, 104.50) | <0.001 |
