Table 4.

Detected masses-rt pairs contributing to the separation of the ethanol treated rat (4 weeks) urine samples from the corresponding controls (+ESI dataset). The trend is referred to ethanol treated animals. (Metabolites in Bold = comparison with authentic standards, metabolites in italic = by comparison with databases).

Fold change denotes the ratio between the average signal from samples from treated animals versus the average signal from samples from control animals. Values >1 denote increase in treated animals. Values <1 denote decrease in treated animals. NA signifies that the ion was not detected in the control samples. Zero value signifies that the ion was not detected in treated samples
