Morphology and density features of eosinophil leukocytes in eosinophilic pneumonia. A case report.

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
We compared the morphological characteristics and density properties of eosinophil leukocytes obtained from the blood and bronchoalveolar lavage fluid of a 29-year-old patient with chronic eosinophil pneumonia during exacerbation. The lavage eosinophils were significantly increased in size when compared with blood cells (surface area: 208 +/- 12 microns 2 versus 161 +/- 13 microns 2). Moreover, eosinophils contained slightly more granules (23.4 versus 20.7 per cell surface area), but no difference was found when the number was corrected for cell size. Electron microscopy revealed a loss of granule contents in eosinophils from both blood and bronchoalveolar lavage. Finally, 61% of the lavage eosinophils were hypodense (with a density less than 1.085 g/ml), whereas 96.3% of the blood cells were normodense. In conclusion, our data demonstrate that in chronic eosinophil pneumonia, eosinophils obtained from bronchoalveolar lavage and blood show differences in both their morphology and density, suggesting that eosinophils during migration into the lung may become activated.
