1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

introduction and importanceCoronavirus disease 2019 (COVID-19) is a pandemic disease that spread rapidly throughout the world and became a major public health concern. Approximately 5-12% of COVID-19 patients require admission to the intensive-care unit (ICU), where they often require oxygen therapy and prolonged intubation. Post-intubation laryngotracheal stenosis (PILS) is a complication that occurs in 10-22% of non-COVID-19 patients after prolonged intubation, while the rate of COVID-19 related PILS remains unknown. Additionally, there is still no consensus in the literature regarding the management modalities for PILS following COVID-19. CASE PRESENTATION: Here we report two cases of tracheal stenosis after prolonged intubation due to severe COVID-19 infection. The first patient was admitted to the ICU and intubated for 21 days; 3 months after discharge, he developed a 3 cm long tracheal stenosis that narrowed 70% of the lumen. The second patient was intubated for 2 months and, 4 months after discharge, developed a 2.5 cm long tracheal stenosis that narrowed 80% of the lumen. CLINICAL DISCUSSION: In both cases, the diagnosis was confirmed by CT scan and Rigid bronchoscopy; then, they were managed successfully with tracheal resection and reconstruction by end-to-end anastomosis.

conclusionIn conclusion, we would like to highlight the importance of suspecting PILS in recovered COVID-19 patients re-presenting with breathing difficulties following weaning from mechanical ventilation; therefore, careful follow-up in such patients is required. Moreover, we would like to point out that the management of tracheal stenosis after COVID-19 appears to be similar to that of tracheal stenosis in general.
