Polymorphonuclear leukocyte apoptosis is accelerated by sulfatides or sulfatides-treated Salmonella Typhimurium bacteria.

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
Neutrophils die by apoptosis following activation and uptake of microbes or enter apoptosis spontaneously at the end of their lifespan if they do not encounter a pathogen. Here we report that sulfatides or sulfatides-treated Salmonella Typhimurium bacteria accelerated human neutrophil apoptosis. Neutrophil apoptosis was examined by flow cytometry. Sulfatides caused prominent increase in percentage of apoptotic cells after 2.5 hrs of incubation. Salmonella Typhimurium bacteria by themselves did not affect the basal level of apoptosis in neutrophil population. When neutrophils were added to S. Typhimurium "opsonized" by sulfatides, apoptotic index significantly increased, whereas the number of phagocyting cells was not influenced. Sulfatides' proapoptotic effect was strongly dependent on the activity of β-galactosidase; inhibition of this enzyme impaired its potency to accelerate apoptosis. These data support the mechanism of neutrophil apoptosis triggering based on sulfatides' ability to accumulate in intracellular compartments and mediate successive increase in ceramide content resulting from β-galactosidase activity.
