Multiple linear regression analysis on trust score.

Standardised	Correlation with trust score^a	Standardised regression coefficient (95% CI)
Usual GP? (1 = no, 2 = yes)	0.23^b	−0.01 (−0.10 to 0.08)

Interpersonal care	0.77^b	0.47^b (0.34 to 0.60)

This GP knows or has checked whether I have followed the treatment or advice recommended on past occasions	0.62^b	0.15^b (0.01 to 0.29)

This GP has always given me the best possible treatment or advice in the past	0.69^b	0.20^b (0.07 to 0.33)

This GP will follow up my progress in the future	0.69^b	0.18^b (0.05 to 0.31)

Age	0.20^b	−0.03 (−0.12 to 0.06)

Sex (1 = male, 2 = female)	−0.14^b	−0.02 (−0.11 to 0.07)

Ethnicity (1 = white, 2 = other)	−0.12	0.03 (−0.06 to 0.12)

Adjusted R² = 0.70.
↵a Significant at P<0.001.
↵b significant at P<0.05.
↵c Correlation calculated is Pearson's r, except for dichotomous variables (for example, sex), where the point biserial correlation (r_pb) was used.
