Summary

This study was designed to compare how often patients with severe COVID-19 developed lung infections while on a ventilator during the first and second waves of the pandemic. It was an observational study that would have looked back at patient records across European ICUs. However, the study was withdrawn before enrolling any participants, so no results are available.
