| Outcomes | Illustrative comparative risks* (95% CI) | No of Participants (studies) | Comments | |
| Assumed risk | Corresponding risk | |||
| Biofeedback assisted relaxation training (RLXT) | Biofeedback assisted breathing re‐training (BRT) | |||
| Pulmonary function ‐ Forced expiratory volume (FEV1) in litres per second | The mean FEV1 in the control group was 0.78 | The mean FEV1 in the intervention group was 0.54 higher (0.15 to 0.93 higher) | 24 (1) | Primary outcome |
| Pulmonary function ‐ Forced vital capacity (FVC) in litres | The mean FVC in the control group was 2.31 | The mean FVC in the intervention group was
0.87 higher (0.09 lower to 1.83 higher) |
26 (1) | Primary outcome |
| Pulmonary function ‐ FEF25-75% in litres per second | The mean FEF25-75% in the control group was 1.39 | The mean FEF25-75% in the intervention group was
0.67 higher (0.1 to 1.24 higher) |

| *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).
