Fig. 6 —Graph illustrates effects of patient age on effectiveness of transforaminal epidural steroid for treatment of sciatica. Transforaminal epidural steroid was most effective in 50- to 59-year-old patients (light gray bars) and least effective in those 70 years old or older (white bars). No patient was younger than 29 years. Black bars = 30- to 39-year-old age group, dark gray bars = 40- to 49-year-old age group, and striped bars = 60- to 69-year-old age group.
