↵a The results are from ‘multivariate’ models including practice scores for all five aspects of experience shown and adjusted by the age–sex–deprivation make-up of practice populations. The main exposure variables for GP Patient Survey items are standardised coefficients (shrunken z scores) instead of the observed practice scores.
↵b The associations highlighted in bold correspond to odds ratio/rate ratio values ≥ a 4% difference from parity (that is, ≤0.96 or ≥1.04).
↵c Urgent referral for suspected cancer is also known as ‘2-week wait’ referral. CI = confidence interval. OR = odds ratio. RR = rate ratio.
