| Comparison | Univariable OR (95% CI) | Adjusted OR (95% CI)* | Mean % high cost in dispensing practices | Mean % high cost in non-dispensing practices | Mean cost per dose in pence, dispensing practices (95% CI) | Mean cost per dose in pence, non-dispensing practices (95% CI) | Total no of prescriptions (items) in England during study month |
