These series can no longer be dealt with using the approximative methods that are appropriate for continuous probability distributions.
Comparisons were made by the Kruskal Wallis or Student's t test as appropriate for continuous variables and by Chi-square or Fisher's exact test for categorical variables.
Results are presented as mean (SD) or median (interquartile range) as appropriate for continuous variables and as absolute numbers for categorical variables.
Bivariate analysis was performed using Student t test, Wilcoxon rank sum test, and Pearson's test as appropriate for continuous and categorical variables.
Group comparisons were done using Fisher's exact tests for categorical variables and Wilcoxon rank sum or Student's t tests, as appropriate, for continuous variables.
Comparisons of the outcomes at baseline and 3 months' follow-up were performed using the McNemar test for binominal variables and the Student t test or the Wilcoxon signed rank test, as appropriate, for continuous data.
Baseline characteristics were compared according to the presence of acidemia using Mann–Whitney test, and Pearson Chi-square test or the Fisher's exact test, as appropriate, for continuous and categorical variables, respectively.
According to calculations of the residence time and thermal efficiency assuming heat recovery with a heat exchanger efficiency of 0.75, the bubbling fluidized bed fluidized by biomass slurry alone was appropriate for continuous biomass gasification using a fluidized bed.
P refers to paired t test or Wilcoxon's Signed Rank Test, as appropriate, for continuous variables and the chi-square test for categorical variables PEEP indicates positive end-expiratory pressure, ZEEP indicates zero end-expiratory pressure, FRC indicates functional residual capacity.
This approach is equivalent to a maximum likelihood estimate assuming a Brownian motion model of evolution and is appropriate for continuous characters.
Survivors and nonsurvivors were compared using the chi-square test for categorical variables and the Student's t-test or Wilcoxon rank-sum test, as appropriate, for continuous variables.
