Secondary and post-hoc outcomes of the systematic review of Tai Chi Chuan training on the QoL and psychological well-being in female patients with breast cancer. (A) TCC-based exercises are superior to other interventions on fatigue when tau ² was calculated by DL estimator in random effect model. Sensitivity analysis using DL + HKSJ as tau ² estimator shows no difference between the two groups. (B) No difference between TCC-based interventions and other interventions on sleep quality. (C) TCC-based exercises are superior to the controls on shoulder function in breast cancer patients. The weights of trials were provided by random effect model applying DL tau ² estimator. BT, Biggerstaff–Tweedie approximate Gamma model; DL, DerSimonian–Laird estimator of tau2; DL+HKSJ, Hartung–Knapp–Sidik–Jonkman (HKSJ) variance correction to DerSimonian–Laird estimator of tau ²; SD, standard deviation; SMD, standardized mean difference; TCC, Tai Chi Chuan. The study ID consists of the first author’s surname, the capital initials of the first author’s first name, and the year the first report of the RCTs was published or submitted as dissertation.
