Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.
Questions and results
Humour‐based interventions compared to active controls for people with schizophrenia
Population: People with schizophrenia
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Average endpoint on a general mental state measured by PANSS total score** Humour‐based interventions vs active controls | no estimate extracted | 1 study · 30 participants | Very low Downgraded: risk of bias, imprecision |
Average endpoint on negative symptoms measured by PANSS negative symptom score*** Humour‐based interventions vs active controls | no estimate extracted | 1 study · 30 participants | Very low Downgraded: risk of bias, imprecision |
Quality of life: clinically important change in general quality of life ‐ as defined by individual studies (long term). Â Humour‐based interventions vs active controls | no estimate extracted | NR | No studies |
Adverse effects/events: at least 1 adverse effect ‐ as defined by individual studies. Humour‐based interventions vs active controls | no estimate extracted | NR | No studies |
