Correlation Between Clinical Assessment and Postmortem Lung Biopsy in Patients With Pulmonary Infiltrates and Respiratory Failure.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPulmonary complications commonly cause mortality in critically ill patients with acute and chronic liver diseases in the intensive care unit. Pneumonia is the most common clinical diagnosis supported by radiological and microbiological results, which are subjective and often with poor yield. The study aimed to correlate clinical diagnosis and postmortem lung histology in patients with liver disease with respiratory failure.
methodsRecords of acute and chronic liver disease patients with respiratory failure-associated mortality and postmortem lung biopsy from September 2009 to March 2020 were analyzed. Clinical diagnosis supported by radiological and/or microbiological data was compared with histology.
resultsOne hundred eight patients (age 46.83±12.96 years), males 80 (74.1%), 63 (58.3%) cirrhosis of the liver, 30 (27.8%) acute-on-chronic-liver-failure, and 9 (8.3%) acute liver failure, were analyzed. Of the 76 patients (70.37 % of the total) with pneumonia, 33 (43.4 %) had histological evidence of pneumonia. Other histological diagnoses in these patients were normal or nonspecific changes in 27 (35.5 %) and alveolar hemorrhage in 13 (17.1 %). In the remaining 32 patients, histological diagnosis of pneumonia was evident in nine patients (28.1%). Using postmortem histology as the gold standard, the sensitivity, specificity, positive predictive value, and negative predictive value for clinical diagnosis of pneumonia were found to be 78.57%, 34.85%, 43.42%, and 71.88% respectively. The kappa statistics for agreement between the two was 0.12 (95% C.I. -0.04 to 0.27) suggesting poor agreement. Age and histological pneumonia predicted significant missed diagnosis.
conclusionThere is poor agreement between clinical diagnosis and postmortem histology. Postmortem lung biopsy helps with the unexplained cause of death.
