Risk factors for limited improvement after total trapeziometacarpal joint arthroplasty

Table 3 Coefficients for independent variables included in the multiple linear regression model for prediction of improvement in VAS at rest and activity, grip strength and DASH score

Outcome	Coefficient	S.E.	95% CI	P value
VAS at activity, R² = 0.08
Preoperative DASH score	−0.05	0.01	−0.08 - -0.02	0.001^*
Male vs female ref	1.73	0.75	0.25–3.20	0.022^*
VAS at rest, R² = 0.13
VAS at activity	0.28	0.10	0.09–0.47	0.004^*
Preoperative DASH score	0.02	0.01	0.00–0.04	0.020^*
Preoperative grip strength	−0.05	0.02	− 0.09 - -0.01	0.009^*
Male vs female ref	1.14	0.56	0.05–2.24	0.043^*
DASH score, R² = 0.07
Preoperative grip strength	−0.42	0.16	−0.73 - -0.11	0.009^*
Grip strength, R² = 0.01
Preoperative VAS at rest	0.53	0.30	−0.08 – 1.10	0.088

The table is divided into four different outcome measures: “VAS at activity”, “VAS at rest”, “DASH” and “Grip strength”. DASH = The disabilities of the arm, shoulder and hand. Grip strength is measured in kg All models are adjusted for baseline measurements, prosthesis, age and gender. Predictors with a p value > 0.09 are not presented in the table
^*Indicates a significant p-value below 0.05
