Summary of findings for the main comparison.

Non‐pharmacological interventions compared with standard care for perceptual disorders
Patient or population: people with perceptual disorders following acquired brain injury (stroke and trauma)
Settings: rehabilitation units
Intervention: non‐pharmacological therapy
Comparison: placebo or no treatment in addition to standard care
Outcomes Illustrative comparative risks* (95% CI) Relative effect (95% CI) No of Participants (studies) Quality of the evidence (GRADE) Comments
Assumed risk Corresponding risk
Standard Perceptual intervention
Independence in activities of daily living
Effects lasting up to 6 months
No data No data None None
Independence in activities of daily living (ADL)
Effects at scheduled end of intervention
The mean Rivermead ADL scale was 10.0 in the only trial to report this outcome The mean Rivermead ADL in the intervention groups was 10.9 33 (1) ++OO low Based on single small study with unclear methods: allocation and interim analysis processes
Independence in activities of daily living (ADL): driving test pass rate
Effects at scheduled end of intervention
Medium risk population OR 1.3 (0.56 to 3.1) 97 (1) +++O moderate Based on single small study
28 per 100 34 per 100 (18 to 55)
*The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). CI: Confidence interval; OR: Odds Ratio.
GRADE Working Group grades of evidence High quality: Further research is very unlikely to change our confidence in the estimate of effect. Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate. Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate. Very low quality: We are very uncertain about the estimate.
