2.5 Data extraction
Three authors (Ma, Pan, and Fan) independent use standard form, the
following data extracted from each article: the first author’s last
name, year of publication, sample size, age, sex, etiology, time
recorded point, the outcome indicators (CRP, Serum amylase, TNF-α,
CRP,PCT,IL-6 levels after treatment, liver and kidney function, APACHEII
