Fig. 1

Difference in measurement between a visual vs a CLINITEK readout for pH and specific gravity. Bland–Altman plots are shown to indicate difference in agreement for a pH for all samples as well as pH stratified by: b light infection intensity and c high infection intensity. The parallel plots are shown for specific gravity (d–f). Dashed black line indicates the mean difference while the grey dotted lines are the upper and lower limits of agreement
