Epidemiological and outcome analysis of COVID-19-associated pneumothorax: multicentre retrospective critical care experience from Qatar.
Article in BMJ open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
objectivesTo study the incidence, characteristics, treatment, associated risk factors and outcome of COVID-19-associated pneumothorax in intensive care unit (ICU).
designRetrospective observational data review.
settingA multicentre study from ICUs of three tertiary care hospitals in Qatar.
participants1788 patients with COVID-19 pneumonia requiring ICU admission from 1 March 2020 to 1 November 2020 were enrolled in this study.
interventionsNot applicable. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary endpoint was to identify the incidence of COVID-19-associated pneumothorax in patients requiring ICU admission. Secondary endpoints were to determine the associated risk factors, treatment, mortality and morbidity.
results1788 patients from 3 centres were reviewed in the study. The total episodes of pneumothorax were 75. Pneumothorax occurred in 4.2% of the patients with COVID-19 pneumonia requiring ICU admission. The majority of the subjects were male (n=72, 96%). The mean age was 55.1 (±12.7 years). The majority of the subjects were nationals of South Asian countries and the Middle East and North Africa regions. 52% (n=39) of the patients were previously healthy without comorbidities before ICU admission. The recurrence rate was 9.3%. The median length of ICU stay was 28 days (20.5-45.8 days). After developing pneumothorax, the length of mechanical ventilation ranged from 6 to 32 days, with a median of 13 days. 44% of patients eventually ended up with tracheostomy. In-hospital mortality in the patients with COVID-19-related pneumothorax was 53.3% (n=40). The odds of mortality in patients with COVID-19 pneumonia with pneumothorax is 7.15 (95% CI 4.45 to 11.48, p<0.0001) compared with those who did not develop pneumothorax. This indicates pneumothorax is a potential independent risk factor associated with mortality in patients with COVID-19 pneumonia requiring ICU admission.
conclusionsPneumothorax is a common complication in patients with COVID-19 requiring ICU admission, associated with poor prognosis and outcome. TRIAL REGISTRATION NUMBER: The study was approved by the Medical Research Centre (MRC) Qatar. (MRC-01-20-1116).
