From: Estimation of normal lung weight index in healthy female domestic pigs
Bland and Altman comparing the real lung weight index of the validation population versus the expected lung weight index calculated with the formula. Mean bias was -0.26 g/kg (95% CI − 0.94–0.43), upper LOA = 3.80 (95%CI 2.72–4.82), lower LOA = − 4.33 (95% CI − 5.54–− 3.12). g grams, kg kilograms, LOA Level of agreement. Figure: black continuous line = mean bias; Black dashed lines = upper and lower LOA; red dotted lines = 95%CI of mean bias, upper and lower LOA
