Selected Liver Markers in Predicting the Severity of Organophosphate and Carbamate Poisoning

Table 4

Differences in RBC cholinesterase and liver transaminases between seriously ill patients (n = 48) and nonseriously ill patients on admission.

Biochemical test	Mann–Whitney U	Z	value	r
RBC cholinesterase	1371.5	−5.20	≤ 0.001	0.40
AST admission	1601.5	−4.382	≤ 0.001	0.34
ALT admission	1974.5	−3.054	0.002	0.24
Direct bilirubin	2401.5	−1.536	0.125	0.12
Total bilirubin	2822.0	−0.036	0.972	0.00

value is significant at 0.05 level; r = effect size; 0.1 = small effect; 0.3 = medium effect; 0.5 = large effect. Z = chi-square.
