Fig. 2From: Influence of strengthened hemoperfusion combined with continuous venovenous hemofiltration on prognosis of patients with acute paraquat poisoning: SHP + CVVH improve prognosis of acute PQ patientsNinety-day survival curves according to treatment after acute paraquat poisoning. Difference in the survival curves among groups with statistical significance was verified and showed by Log-Rank, χ2 = 170.447, P = 0.000. Comparison between SHP + CVVH and control: χ2 = 118.084, P = 0.000; comparison between SHP + CVVH and HP: χ2 = 11.003, P = 0.001; comparison between SHP + CVVH and CVVH: χ2 = 28.549, P = 0.000; comparison between SHP + CVVH and SHP: χ2 = 5.740, P = 0.017Back to article page
