Figure 1. Mean differences in GPs’ NHS-recorded prescribing volumes of antibiotics, opioids, gabapentin and benzodiazepines, measured over 6 months, adjusted by patient size of GPs’ practice and their individual proportion of drug-specific prescriptions in association to their (A) level of risk literacy, (B) level of conflicts of interest and (C) perception of harms in drug-specific low-value prescription scenarios (excluding gabapentin). Error bars show standard errors (SE) of the means. *Two-sided significance at p<0.05. GPs, general practitioners; NHS, National Health Service.
