It is very uncertain whether heated humidification + fixed CPAP changes withdrawals (parallel group trials/first arm cross‐over trials) compared with fixed CPAP alone (very low certainty).

Heated humidification + fixed CPAP vs fixed CPAP

Adverse events (machine tolerability outcomes) assessed as number of participants experiencing a blocked nose · adults with a diagnosis of sleep apnoea

Heated humidification + fixed CPAP may leads to lower adverse events (machine tolerability outcomes) assessed as number of… compared with fixed CPAP alone (low certainty).
