  		Figure 1. One-month behavior change among intervention and control patients.

Note: The bars portray the percentage of patients whose behavior improved at 1 month (n = number of patients whose behavior changed). The comparison is among patients who indicated a change in behavior. Proportional change was computed as behavior improved ÷ (100% - no change). Some round-off error may have occurred. The P value is based on Fisher’s exact test,13 comparing intervention with control percentage improvements.
