Summary of findings 7. Walking versus lying.
| Walking versus lying for reducing risk of maternal hypotension during spinal anaesthesia for caesarean section | |||||
| Patient or population: women having spinal anaesthesia for caesarean section Setting: hospital setting in Australia Intervention: walking Comparison: lying | |||||

| Maternal hypertension requiring intervention | No studies reported this outcome. | ||||

| *The risk in the intervention group (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: We are very confident that the true effect lies close to that of the estimate of the effect Moderate quality: We are moderately confident in the effect estimate: The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different Low quality: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect Very low quality: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect | |||||
