Table 1 Number of dogs (n) with mild/moderate or severe hip dysplasia divided into three different weight groups, where the hip status and body weights are used as stratification factors.

From: Two years follow-up study of the pain-relieving effect of gold bead implantation in dogs with hip-joint arthritis
