Linear relationships of objective measurements of skinfold thickness and total body fat percentage (BF%) evaluated by dual-energy X-ray absorptiometry (DEXA) in 23 privately owned newly euthanized dogs.
| Statistical model | Coefficients of linear variables | Explained variation | |||
|---|---|---|---|---|---|
| Simple linear models (lm) | Estimate skinfolds | SE skinfolds | p-value skinfolds | R2 Adj. | R 2 |
| lm (BF% ~ dorsal neck) | 1.35 | 0.94 | 0.16 | 0.05 | 0.09 |
| lm (BF% ~ axillar rib) | 0.97 | 1.15 | 0.41 | −0.01 | 0.03 |
| lm (BF% ~ lumbar back) | 1.12 | 1.12 | 0.33 | 9.5 × 10−6 | 0.05 |
lm, linear model; BF%, total body fat percentage; SE, standard error; R2 Adj., coefficient of determination adjusted; R2, coefficient of determination. Data were analyzed by linear models with objective measurements of skinfold thickness as x-variables and total body fat percentage (BF%) as y-variable.
