Effects of primary care C-reactive protein point-of-care testing on antibiotic prescribing by general practice staff: pragmatic randomised controlled trial, England, 2016 and 2017.

Table 5 shows an estimated 19% reduction (95% CI: −17 to 34) in the odds of prescribing in the three high-fidelity intervention practices compared to non-intervention practices when considering the four diagnoses and a 31% reduction (95% CI: −38 to 65) when considering just cough diagnoses; both failed to reach statistical significance.
