Fig. 1 Patient disposition and termination by treatment group. a44 patients did not require weaning of IT medications and entered the stabilization period directly. (Of the 44 patients who did not enter weaning, 23 had their pump implanted less than a month before the study; one, 3 months before consent; and the other 20 had their pumps for greater than 200 days. Of these 44 patients, three were on low-dose opioid monotherapy and the other 41 had no IT drugs at screening). b184 patients completed the weaning period and entered the stabilization period.
