Intervertebral disc disease in Dachshunds radiographically screened for intervertebral disc calcifications

Table 3 Effect of intervertebral disc calcification (IDC) grade on intervertebral disc disease (IDD) in 193 Dachshunds radiographed for IDC

Grading of calcification (IDC grade)	OR (CI 95%)
1 versus 0	3.3 (1.0 – 1.4)*
2 versus 0	5.3 (1.5 – 19.1)**
2 versus 1	1.6 (0.6 – 4.0)ns
3 versus 0	17.9 (5.2 – 60.9)**
3 versus 1	5.4 (5.2 – 12.5)**
3 versus 2	3.4 (1.2 – 9.4)*

Disease was measured by a questionnaire where the owner was asked to report symptoms indicative of IDD and also confirmed and treated by veterinarians. Grade 0 (0 calcifications), Grade 1 (1 – 2 calcifications), Grade 2 (3 – 4 calcifications), Grade 3 (≥5 calcifications).
OR = odds ratio, CI = confidence interval, * = P ≤ 0.05, ** = P ≤ 0.01, ns = not significant.
