Table 1.
Demographic data for the dogs of the total group, test set, and training set
| Variable | Total Group (n = 1719) | Training Set (n = 1200) | Test Set (n = 519) | P‐Values |
|---|---|---|---|---|
| Age (years) | 6.9 (0.04–19.0) | 6.8 (0.04–19.0) | 7.0 (0.16–16.0) | 0.52 |
| Weight (kilograms) | 18.0 (0.4–96.0) | 17.0 (0.4–94.0) | 20.0 (0.8–96.0) | 0.26 |
| BCS (9‐point scale) | 5 (1–9) | 5 (1–9) | 5 (1–9) | 0.04* |
| Sex | 0.97 | |||
| Neutered Males | 723 (42.0%) | 509 (42.4%) | 214 (41.2%) | |
| Intact Males | 166 (9.7%) | 114 (9.5%) | 52 (10.1%) | |
| Spayed Females | 718 (41.8%) | 499 (41.6%) | 219 (42.2%) | |
| Intact Females | 112 (6.5%) | 78 (6.5%) | 34 (6.5%) | |
| Calcium Status | 0.56 | |||
| Hypocalcemic | 280 (16.3%) | 202 (16.8%) | 78 (15.0%) | |
| Hypercalcemic | 99 (5.8%) | 71 (5.9%) | 28 (5.4%) | |

Table entries represent median values (minimum–maximum) for continuous variables (age, weight, and body condition score) and number of dogs (percent of dogs) for categorical variables (sex and calcium status). Calcium status categories were determined based on measured ionized calcium values. Significant differences between the dogs of the training set and those of the test set, as assessed via the Mann–Whitney (age, weight, and body condition score) and chi‐square (sex and calcium status) tests, were defined by a P‐value<0.05 and are indicated by *.
