A microscopic study of the lung of Testudo graeca (Chelonia).

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
The lung of the tortoise, Testudo graeca (Chelonia) was studied by means of light and electron microscopy, histochemistry and immunocytochemistry. The lung showed the typical faviform structure of the reptilian lung. Three orders of trabeculae were observed. The epithelium of primary and secondary trabeculae was composed of ciliated, mucous, basal and endocrine cells. Mucous cells contained sialo- and sulpho-mucins and were reactive to the lectins Con-A, WGA, DBA, PNA and SBA. Endocrine cells were observed as solitary cells or forming neuroepithelial bodies. By means of immunocytochemistry, endocrine cells were demonstrated to contain serotonin. In the gas-exchange area Types I and II pneumonocytes and undifferentiated cells were observed. Free macrophages were detected in the faveolar lumen. The lung interstitium contained smooth muscle cells, fibrocytes, pigment cells, myelinated and unmyelinated nerves and intrapulmonary ganglia. Nerve terminals containing clear and dense-cored vesicles were observed in the adventitia of the blood vesicles and interspersed between the smooth muscle bands. The lung of the hibernating specimens showed a marked vacuolisation of pneumonocytes. In conclusion, the lung of Testudo graeca showed a complex histological organisation. Marked differences from mammalian lung were found.
