| Mortality (pooled) | 315 per 1000 | 346 per 1000 (296 to 406) | RR 1.10 (0.94 to 1.29) | 1142 (nine studies) | ++-- LOW Due to serious risk of bias and serious indirectness | Six out of nine studies compared iNO with usual care rather than placebo Highly variable dose and duration of iNO and inclusion criteria |
