Study Purpose: The purpose of this randomized controlled trial was to determine theimpact of an app-based digital care program to treat chronic lower back paincompared to usual treatment. Post intervention pain scores were measured usingKorff pain measurement scale that ranges from 0 (minimum) to 100 (maximum). Theresults for this study are summarized in the table below.Table: Mean Pain ReportsChange in meanChange in meanMean differenceP- valuepain scorepain score(95% CI)Intervention groupControl group(n=113)(n=64)Korff pain score-25.31.6-26.9 (-33.8, -20)<0.001Answer the following questions using data from the table above:1.
