	Step change (β₆) [99% Wald CI]	Change in trend (β₇) [99% Wald CI]
Odds of being reimbursed for an analgesic or NSAID, in intervention compared to control group (PO1)	0.9980 [0.9834; 1.0128]	0.9889 [0.9767; 1.0013]
Average defined daily dose of paracetamol per patient reimbursed for paracetamol per month, in intervention compared to control group (PO2)	− 0.3287 [− 1.0491; 0.3917]	0.0386 [− 0.1973; 0.2745]
Odds of being reimbursed for a recommended NSAID when reimbursed for any NSAID, in intervention compared to control group (PO3)	1.1903*[1.0757; 1.3171]	0.9901 [0.9719; 1.0086]
Odds of being reimbursed for an NSAID and a PPI when reimbursed for an NSAID, in intervention compared to control group (PO4)	1.0217 [0.9243; 1.1294]	0.9926 [0.9685; 1.0173]

Step change difference in step change between the intervention and control group immediately after the intervention; change in trend difference between the change in trend between the intervention and control group after the intervention; CI confidence interval, NSAID nonsteroidal anti-inflammatory drug, PPI proton pump inhibitor; *p value < 0.01; underlined < 0.01 in all four analyses (ITT, ITT-V1, ITT-V2 and PPR)
