Correlation plots between UpTime and HUA, separated by disease level. Linear regressions were calculated using least squares by R Studio’s ggscatter function. Blue, grey, and red colored regions indicate the 95% confidence interval for each regression line. The R² values were: (Control) R² = 0.23, (Moderate) R² = 0.004, and (Severe) R² = 0.036
