Table 3 Effect of additional AHA supervised exercise: summary of meta-analyses

From: The effect of delegation of therapy to allied health assistants on patient and organisational outcomes: a systematic review and meta-analysis

Outcome No. of trials No. of participants MD/RR (95%CI), I2 Quality of evidence
(GRADE)
Discharge home 4 [29, 32, 36, 44] 696 RR 1.28 (1.03 to 1.59), I2 = 60% Very Low a, b, d
Acute length of stay (days) 6 [29, 32, 36, 39, 42, 44] 1787 MD − 0.28 (− 0.54 to − 0.03), I2 = 0% Low a, d
  1. AHA Allied health assistant, MD Mean difference, RR Risk ratio, GRADE Grading of Recommendations Assessment, Development and Evaluation
  2. Negative MD favours additional AHA intervention group: Acute length of stay
  3. RR > 1 favours additional AHA intervention group: Discharge home
  4. Reason for downgrade: a – risk of bias: majority of trials have at least 4 items on the internal validity scale of the Downs and Black checklist that were not met; b – heterogeneity: I2 ≥ 25%; c – imprecision of result: large CI; d - majority of studies not RCT design
