*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). FEV₁: forced expiratory volume in one second; FVC: forced vital capacity; NA: not applicable; NR: not reported; P aeruginosa: Pseudomonas aeruginosa; RCT: randomised controlled trial | ||||||
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. |
1. Downgraded once due to risk of bias; methodological information was limited and unclear in the included study and there was a high risk of bias due to lack of blinding.
2. Downgraded once due to applicability: the included study recruited only children; results are not applicable to adults.
3. Downgraded once due to imprecision: no numerical results available.
