Change in (mean and standard deviation) lameness relative to baseline in six horses challenged with 2 ng lipopolysaccharides in the radiocarpal joint at hour − 2. At hour 0 either saline (filled circles) or dexamethasone (open circles) was injected in the LPS challenged joint. The horses received one dose dexamethasone sodium phosphate each. The doses were 0.01, 0.03, 0.1, 0.3, 1, and 3 mg administered in an injection volume of 2 mL. Upper plot (a): change in minimum head height differences (HDmin) scored objectively. Lower pot (b): change in American Association of Equine Practitioners (AAEP) lameness score
