Piecemeal degranulation in human tumour pheochromocytes.
Article in Journal of anatomy, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Piecemeal degranulation (PMD) has been recognized in two cases of human pheochromocytoma from the adrenal medulla, which were studied by transmission electron microscopy. Tumour pheochromocytes presented a highly characteristic cytoplasmic admixture of normal resting granules, swollen granules with eroded matrices and enlarged empty containers. Chromaffin granules that appeared to be normal and altered granules maintained their individual structure, and did not fuse with each other or with the plasma membrane. In accordance with the currently accepted model for granule discharge during PMD, electron-dense or clear vesicles 30-150 nm in diameter were seen either attached to the surface of chromaffin granules and the plasma membrane or free in the cytosol. This is the first description of PMD in human adrenal chromaffin cells and, in addition, is the first report of PMD in tumour secretory cells. These findings add further to the concept that PMD may have a broader spectrum of expression than hitherto recognized.
