Summary of findings 5. Summary of findings: needle acupuncture versus valproate.
Needle acupuncture compared with valproate for epilepsy | ||||||
Patient or population: participants with epilepsy (one included study only recruited children with absence epilepsy while another included study recruited both children and adults with generalised epilepsy) Settings: hospital inpatients and outpatients Intervention: needle acupuncture Comparison: valproate | ||||||

Post‐treatment quality of life (QOLIE‐31 score, which has a range of 0‐200, with higher score indicates better quality of life) (follow‐up: 3 months) |
The mean post‐treatment quality of life across control groups ranged from 170.22 to 172.6 points. | The mean post‐treatment quality of life in the intervention group was 12.04 points higher (4.05 points higher to 20.03 points higher). | 100 (1) |

*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; RR: Risk 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. |
a. Evidence from RCT downgraded by two levels because of high risk of bias in study design and imprecise result.
