Spatially periodic discrete contact regions in polylysine-induced erythrocyte-yeast adhesion.
Article in Cell biophysics, 1988. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Cell-cell adhesion occurs when human erythrocytes and yeast cells are suspended together in suprathreshold concentrations of polylysine in saline. The threshold polycation concentration for adhesion depends on cell concentration and decreases with increasing polycation molecular weight. The threshold concentration was similar for erythrocyte-erythrocyte adhesion and for yeast-erythrocyte adhesion. Transmission electron micrographs show that the erythrocytes adhere to yeast as if to engulf the cell. The regions of close contact between the erythrocyte membrane and the yeast cell walls are spatially discrete. The contact separation distance for the asymmetric erythrocyte-yeast adhesion is very similar to that (0.83 micron) observed when polylysine-induced adhesion occurs in the symmetrical erythrocyte-erythrocyte system. The spacing is attributed to the growth of a squeezing wave as an interfacial instability, on the intercellular aqueous layer. Freeze-fracture electron microscopy of cells that were not fixed during preparation for microscopy confirms the discrete nature of contacts between polylysine treated erythrocytes.
