Patients were enrolled between June 2003 and February 2008. Sixty-three patients (61%) had lateral epicondylosis, 17 patients (16%) had trapeziometacarpal arthrosis, and 24 patients (23%) had de Quervain syndrome. Each patient completed a set of questionnaires at time of enrollment. Bivariable and multivariable analyses were used to determine factors associated with missed research appointments.  Results:  Fourteen patients (13%) did not return for the first follow-up and 33 patients (32%) did not return for the second follow-up. The best multivariable logistic regression model for missing the first research visit explained 35% of the variability and included younger age, belief that health can be controlled, and no college education. The best model for missing the second research visit explained 17% of the variability and included greater pain intensity, less personal responsibility for health, and diagnosis (trapeziometacarpal arthrosis and de Quervain syndrome). Conclusions:  Younger patients with no college education, who believe their health can be controlled, are more likely to miss a research appointment when enrolled in a randomized placebo injection-controlled trial. }, keywords = {De Quervain syndrome,Lateral epicondylosis,Loss to follow-up,Missed research appointments,Randomized placebo-controlled trial,Trapeziometacarpal arthrosis}, url = {https://abjs.mums.ac.ir/article_3230.html}, eprint = {https://abjs.mums.ac.ir/article_3230_92bca7523b45f3f533bc5590d4f84a3b.pdf} }
