Groups sharing capital letters (A, B, C, D) are not significantly different as analysed by ANOVA Kruskal–Wallis test for multiple comparisons (family wise α = 0.05).
AST, aspartate aminotransferase; KEB, coefficient of energy balance; LDH, concentrations of lactate dehydrogenase catalytic activities in pleural effusions; n, number of patients
