From: Estimation of normal lung weight index in healthy female domestic pigs
Body weight versus lung weight index regression and exponential function fitting the training population (white points) and piglets belonging to the validation population (black points). The exponential function is expressed by the black dashed line. 95% CI of the function are represented as black dotted lines. Upper 95% CI function: Lung Weight Index = 28.84 * 10 (− 0.009*Body Weight). Lower 95% CI function: Lung Weight Index = 23.44 * 10 (− 0.013*Body Weight). g grams, kg kilograms, CI confidence intervals
