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.

Treatment group	Number of dogs (n)	Drop Out (n)	Weight group (kg)	Mild or Moderate hip dysplasia (n)	Severe hip dysplasia (n)	Total (n)
GG	36	2	≤ 20.0	1	3	4
			20.1 – 34.9	8	8	16
			≥ 35.0	8	6	14
PG	33	1	≤ 20.0	0	1	1
			20.1 – 34.9	7	9	16
			≥ 35.0	10	5	15
PC	9	2	≤ 20.0	0	0	0
			20.1 – 34.9	4	0	4
			≥ 35.0	0	3	3
Total	78	5		38	35	73

The GG group = gold implantation from Day 0 to 24 months, the PG group = placebo treatment the first six blinded month and then 18 months gold bead implantation, PC group = placebo treatment the first six blinded month and as a control group the next 18 months
