On bivariate analysis female gender, polymorphic VT, edema, intubation, baseline hemoglobin levels, WBC counts hazard ratios (HR) 2.22 [0.95-5.18], 2.44 [1.18-5.08], 13.49 [1.82-99.85], 17.54 [2.38-129.44], 1.25 [1.05-1.47], 1.06 [1.01-1.11] respectively. multivariate analysis, level independent adjusted HRs 3.88 [1.02-14.77], 9.9 [0.95-103.25], 1.47 [1.2-1.79] Conclusion: for conservative region is comparable international figures.
