He⁻⁻ADSS (clinically significant haematoma excluded) post-operative pain prediction score from the BRUISE-Control Trials (the most severe post-operative pain scores were used to perform the above analyses)

Variables	Beta	Beta after inflationa	Points
Age <65 years	0.68	2.6	3
De novo surgery	0.47	1.82	2
BMI <20 kg/m2	0.55	2.13	2
Female sex	0.26	1	1

BMI, body mass index; CSH, clinically significant haematoma.

^aBeta coefficient was inflated by dividing the smallest beta coefficient (0.27), and then points were derived by rounding to the nearest integer. The BRUISE-Control He⁻⁻ADSS and He⁺⁺ADSS scores post-operative pain risk score were developed based on the final risk prediction model (He, CSH; A, age; D, de novo surgery; S, slim—BMI <20 kg/m²; and S, sex—female).
