TNF and bacterial infectious disease: As compared to non-survivors, survivors seemed to be younger (P < 0.001) and had higher PTA (P < 0.001), lower TBil (P < 0.001), lower Amon (P = 0.003), lower BUN (P < 0.001), lower Cr (P < 0.001), higher AFP (P = 0.004), less bacterial infection (P = 0.003), higher IL10 (P < 0.001) and TNFα (P < 0.001), and lower iMELD socre (P < 0.001).
