^a 1 cc of "cortisone" (i.e., a corticosteroid of any given type) represents the equivalent of 40 mg of Depo-Medrol.

^b There are no significant differences in cortisone doses between the three physician groups.

^c When compared to each of the other groups, orthopaedic surgeons use significantly (p < 0.01) greater volumes of local anesthetic in each location. Rheumatologists and PCSMs/PMRs do not differ in anesthetic volumes (p > 0.3).
