Statistical Analysis Data are presented seeing that numbers and %ages, means and standard deviations, medians and interquartile ranges, or proportions with 95 percent confidence intervals. Appropriately, chi-square tests for equivalent proportion, Student’s t-check, or the Wilcoxon rank-sum test were used to check variations. No assumptions were made for lacking data, with multivariable analysis performed on data from sufferers who had full data only . To identify independent variations at baseline that may exist between sufferers with SIRS-positive serious sepsis and those with SIRS-negative serious sepsis, we applied multivariable logistic regression to data from all the patients with severe sepsis with SIRS-positive position because the outcome .Pusey, D.Sc., F.Med.Sci., Alan D.
