GPT and lymphopenia: On the categorical analysis of the laboratory markers, those who had severe disease had significant leukocytosis (> 10,000 cells/ μL) (30.1% vs 9.8% p < 0.002); lymphopenia (<1000 cells/ μL) (63% vs 21.6% p < 0.000); raised neutrophil-to-lymphocyte ratio of ≥ 10 (28.8% vs 8.8% p < 0.001); thrombocytopenia (<150,000 cells/ μL) (16.4% vs 5% p < 0.013); elevated ALT (35.7% vs 14.1% p < 0.001); elevated AST (76.5% vs 28.1% p < 0.0001); and elevated urea (31.9% vs 16.5% p < 0.025) compared to those who had non-severe disease.
