Web-Based Return of Individual Patient-Reported Outcome Results Among Patients With Lymphoma: Randomized Controlled Trial

Web-Based Return of Individual Patient-Reported Outcome Results Among Patients With Lymphoma: Randomized Controlled Trial

The P value for overall model effects was set at .05, and for specific contrasts at .01, lowering the risk of type I errors as a result of multiple testing. In the iterative process of variable selection, a priori selected covariates (age, sex, cancer type, and treatment) were removed from the model as they were nonsignificant and had no confounders.

Web-Based Self-Management for Patients With Lymphoma: Assessment of the Reach of Intervention of a Randomized Controlled Trial

Web-Based Self-Management for Patients With Lymphoma: Assessment of the Reach of Intervention of a Randomized Controlled Trial

Patients invited to participate did not significantly differ from all patients selected from the NCR in terms of age (P=.38) and sex (P=.07) (Table 1). Among the 892 invited patients, 456 patients (51.1%) responded and completed either a web-based or paper questionnaire. The mean age of all respondents (Table 1) was comparable with that of nonrespondents (63.8 years, P=.43), and the majority of the respondents were also men.

“Am I normal?” The Wishes of Patients With Lymphoma to Compare Their Patient-Reported Outcomes With Those of Their Peers

“Am I normal?” The Wishes of Patients With Lymphoma to Compare Their Patient-Reported Outcomes With Those of Their Peers

P We used Fischer exact tests or t tests to compare differences in sociodemographic and clinical characteristics between respondents and nonrespondents and between patients who wished and those who did not wish to receive PRO feedback. To evaluate whether scores were on average comparable with those of a lymphoma reference cohort, we compared patients’ mean EORTC QLQ-C30 and HADS scores with mean scores of a lymphoma reference group using analysis of covariance with age and sex as covariates.
