Enzymatic assay results for two paediatric syrups (Calprofen and Dimetapp) spiked with different percentages of EG. (a) End-point 340 nm absorbance readings of NADH after using alcohol dehydrogenase and aldehyde dehydrogenase. (b) End-point 571 nm absorbance readings after additionally using glycolate oxidase in the glycolic acid assay. Error bars show the standard deviations of two replicates. Two-way ANOVA with Dunnett’s multiple comparison. ns, not significant; ***p < 0.005; ****p < 0.0001.
