Strengths and limitations
CABM
We identified several limitations in our study. First, we collected data related to QOL only at 12 months. Then we did not have data regarding QOL at baseline, preventing us from making an intra-subject comparison between baseline and 12 months. It might also be interesting to have a longer-term follow-up of CABM patients to have more information on the support to be recommended. Second, since the findings were based on self-report measures collected by phone, it may have introduced a response bias, social desirability bias, even though questionnaires were anonymous and standardized. Moreover, questionnaires could be answered by proxies or by general practitioners that may have introduced a measurement bias, but fortunately this only concerns very few patients. Regarding our QOL models, except for physical health, variables included in models explain a relatively small proportion of the variance in QOL. The integration of psychosocial factors would enrich our models beyond the clinical characteristics of individuals.
