Cells responding to chemoattractant on a structured substrate.
Article in Biophysical journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 migration on an adhesive substrate surface comprises actin-based protrusion at the front and retraction of the tail in combination with coordinated adhesion to, and detachment from, the substrate. To study the effect of cell-to-substrate adhesion on the chemotactic response of Dictyostelium discoideum cells, we exposed the cells to patterned substrate surfaces consisting of adhesive and inert areas, and forced them by a gradient of chemoattractant to enter the border between the two areas. Wild-type as well as myosin II-deficient cells stop at the border of an adhesive area. They do not detach with their rear part, while on the nonadhesive area they protrude pseudopods at their front toward the source of chemoattractant. Avoidance of the nonadhesive area may cause a cell to move in tangential direction relative to the attractant gradient, keeping its tail at the border of the adhesive surface.
