Characterization of Markers in Blood Tests of Patients With Pleural Effusion and Their Correlation to Different Etiologies.
Article in Journal of community hospital internal medicine perspectives, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: To investigate the etiology of pleural effusion, a variety of examinations are performed, including invasive ones: Thoracentesis is an invasive procedure to remove fluid or air from the pleural cavity for diagnostic or therapeutic purposes. Until now, there are no blood markers that can help us diagnose the type of pleural effusion without the need for pleural puncture or drainage. Aims: The aim of this study was to investigate the relationship and the utility of the new inflammatory markers taken from complete blood count (CBC) to differentiate between the various types of pleural effusion before the invasive procedure decision. Material and methods: This is an observational retrospective study. Data was collected from medical records of patients aged 18-90 admitted in Ziv Medical Center, Safed, Israel that were diagnosed with pleural effusion from 2013 to 2019. Of those patients, of whom inflammatory markers from blood counts and thoracentesis results were obtained, the outcomes were compared with the diagnosis type of pleural effusion. Results: This study involved 391 patients, 256 suffered from exudate type effusion, their median age was 72 years, while 135 suffered from transudate effusion, their median age was 80 years. Those with exudate effusion had higher levels of CRP, platelets, neutrophils, and lymphocytes in blood, whereas those with transudate effusion had higher levels of MPV and RDW in blood. Other blood markers such as NLR and PLR were not statistically significant, but were also higher in the blood of patients with exudate effusion. Conclusion: An evaluation of simple and inexpensive measurements of blood count such as platelets, neutrophils, lymphocytes, MPV, RDW may provide insight into the etiology of pleural effusion.
