*The basis for the assumed risk (e.g. the mean 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; SMD: standardised mean difference | ||||||
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. |
aDisability is outcome is reported as a standardised mean difference. The sample size is large (> 400) and the 95% CI overlaps no effect and therefore we have downgraded for imprecision.(GRADE 2013). bHeterogeneity may be due to clinical variation ‐ Chollet 2011 and Marquez Romero 2013 give 20 mg fluoxetine for 90 days and FOCUS Trial Collaboration 2018 gives 20 mg for 180 days; methodological differences (when the outcomes are measured) ‐ Chollet 2011 and Marquez Romero 2013 measure at 90 days and FOCUS Trial Collaboration 2018 measures at 180 days; or population differences ‐ Chollet 2011 recruited participants only with ischaemic stroke with motor deficits, Marquez Romero 2013 recruited only participants with haemorrhagic stroke and FOCUS Trial Collaboration 2018 recruited all pathological subtypes. The trials were performed in different countries where other factors such as the amount of therapy might influence outcome. These are plausible explanations for the observed heterogeneity and we have therefore we have not downgraded the evidence (Schünemann 2017). cThe optimal information size criterion (FOCUS Trial Collaboration 2018) has been met and the 95% CI overlaps no effect; we have therefore downgraded for imprecision (GRADE 2013). dNeurological deficit outcomes reported as a SMD. Sample size is < 400 and we have therefore downgraded for imprecision (GRADE 2013). eStudies used different measures of depression. This variability in study design may have contributed to variability in intervention effects. fThe sample size is large (> 2000) but the 95% CI overlaps no effect; we have therefore downgraded for imprecision (GRADE 2013). gStudies are small with too few events and wide CIs; we have therefore downgraded for imprecision (Schünemann 2017).
