Urinary albumin concentrations at different time points in controls and paraquat treated rats. Note that albumin concentration (y axis) values are actual raw values (not logarithmic values). Y axis is formatted on log scale to improve the visibility of data points. An increase urinary albumin concentration was observed as histopathology grades increased in paraquat treated rats. Each symbols indicate biomarker concentrations from individual rats at specific paraquat dose levels. The histopathology grades [28] are displayed on a scale of 0 (normal) to 7 (severe) [grade 1 (white), grade 2 (yellow), grade 3 (blue), grade 4 (green), grade 5 (red), grade 6 (purple) and grade 7 (black)]
