  		Figure 4a: Graphs show RAND 36-Item Health Survey scores for (a) physical functioning and (b) bodily pain in two treatment groups of the DIST study and in age-matched controls. Solid line signifies group with primary stent placement; dotted line, group with PTA and selective stent placement; and dashed and dotted line, age-matched controls. At long term, scores of patients treated with selective stent placement were not different from data in age-matched controls, whereas patients with primary stent placement had lower scores.
