Figure 1. Hot-map of total citations for classic citations in clinical trials of exercise training and CKD. Note: we coded classical citations from highest to lowest total number of citations, consistent with the numbering in Table S1.

Figure 3. Study characteristics of 30 classic citations. Note: (A) Over half of the 30 citation classics were randomized controlled trials, with six single-arm trials and quasi-experimental studies, respectively. (B) For the study population, more than 3/4 were hemodialysis-dependent CKD patients, only one study recruited kidney transplant recipients, and no separate clinical studies included peritoneal dialysis patients. (C) Regarding exercise type, aerobic exercise was reported in 55% of the studies, with a comparable proportion of combined exercise and resistance training. (D) Thirty citation classics reported exercise durations that fluctuated considerably between years, with the longest being 48 weeks.
