Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Unclear risk | Described as randomised but generation of sequence not described. |
Allocation concealment (selection bias) | Unclear risk | Not discussed. |
Blinding (performance bias and detection bias) All outcomes | Unclear risk | Not discussed. |
Incomplete outcome data (attrition bias) All outcomes | High risk | 13 drop outs identified with reason of haemoptysis given for 3 participants. Haemoptysis necessitating cessation of ACT occurred in 1 (12.5%) Metaneb participant and 2 (40%) HFCC participants.No information given on remaining 10 drop outs. |
Selective reporting (reporting bias) | Unclear risk | Abstract only, not possible to compare protocol with full paper. |
