Effectiveness and safety of structured exercise vs. no exercise for asymptomatic aortic aneurysm: systematic review and meta-analysis

Figures

  Figure 1. PRISMA flow chart for the review. This figure shows the PRISMA flow chart illustrating the processing of searching for, selecting, excluding, and including studies. There were three references from the same studies: two25,26 from Myers et al.11 and one27 from Barakat et al.,28 resulting in eight references from five original studies.

  Figure 2. Number of patients referred for surgery at any time during surveillance. This figure shows patients referred for surgery at any time during the surveillance period. They were described at 12 weeks (1.2.1) and at 12 months (1.2.2). M-H, Mantel–Haenszel; Random, random-effects model; CI, confidence interval; Events, number of patients referred for surgery; Total, total number of patients; Total (95% CI), effect size at 95% confidence interval.

• 

  Figure 3. Exercise time during surveillance. (A) Exercise time during surveillance at 12 weeks (exercise vs. no exercise). (B) Exercise time during surveillance at 12 months (exercise vs. no exercise). IV, inverse variance; Random, random-effects model; CI, confidence interval; Total, total number of patients; Total (95% CI), effect size at 95% confidence interval.

  Figure 4. Change in anaerobic threshold and peak VO2 during surveillance. (A) Change in total anaerobic threshold values at 7 and 12 weeks during surveillance (exercise vs. no exercise). (B) Peak VO2 during surveillance at 7 and 12 weeks (exercise vs. no exercise). IV, inverse variance; Random, random-effects model; CI, confidence interval; Total, total number of patients; Total (95% CI), effect size at 95% confidence interval.

  Figure 5. Thirty-day mortality after surgery in patients in the preoperative study. This figure compares 30-day mortality after surgery in patients in the exercise and no exercise groups during the preoperative period. EVAR, endovascular aneurysm repair. Comparison 2 involves the subset treated with EVAR (2.5.1) and the subset treated with open surgery (2.5.2). M-H: Mantel–Haenszel; Random, random-effects model; CI, confidence interval; Events, number of deaths up to 30 days after surgery; Total, total number of patients; Total (95% CI), effect size at 95% confidence interval.
