↵* For cost conscious score, only one pairwise comparison was significant: physicians who were somewhat familiar had significantly higher score compared to those unfamiliar with the Choosing Wisely campaign (P = .002).
For low-value service use score, even though the overall test was significant (P = .02), none of the pairwise comparison was significant.
