Table 5. Estimated reduction in the odds of prescribing (total antibiotics) in intervention practices, compared to non-intervention practices, C-reactive protein point-of-care testing, Northern England, 2016–17 (n = 1,186).

	Estimated reduction in the odds of prescribing: total antibiotics (OR, 95% CI)
Diagnosis included	All intervention practices	High-fidelity intervention practices	Low-fidelity intervention practices
Lower respiratory tract infection, bronchitis, chest/respiratory infection, cough (n = 1,186)	−12% (0.88; 95% CI: 0.66–1.16)	−19% (0.81; 95% CI: 0.66–1.17)	−7% (0.93; 95% CI: 0.67–1.30)
Cough (n = 594)	−21% (0.79; 95% CI: 0.46–1.35)	−31% (0.69; 95% CI: 0.35–1.38)	−13% (0.87; 95% CI: 0.46–1.65)

CI: confidence interval; OR: odds ratio.
