Mean ± SD values for FV/AV, FVIA/FV, FVIA/AV, OA score,^* and DI in 1 hip joint from each of 46 mixed-breed hound-type dogs with hip joint OA as measured at 16, 32, and 104 weeks of age.

Variable	16 weeks	32 weeks	104 weeks
FV/AV	0.85 ± 0.12a	1.04 ± 0.18b	1.01 ± 0.26b
FVIA/FV	0.34 ± 0.13b	0.26 ± 0.16a	0.35 ± 0.14b
FVIA/AV	0.29 ± 0.10a,b	0.28 ± 0.17a	0.34 ± 0.11b
OA score	0.00 ± 0.00a	0.65 ± 1.12b	0.93 ± 1.24b
DI	0.65 ±± 0.15	0.74 ± 0.19	0.70 ± 0.22

^*Radiographs of hip joints were assigned OA scores for degree of degenerative joint disease as follows: none = 0, mild = 1, moderate = 2, and severe = 3.
