Membrane skeleton involvement in cell fusion kinetics: a parameter that correlates with erythrocyte osmotic fragility.
Article in Biophysical journal, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Spectrin levels in erythrocytes have been related to several biomechanical and biophysical membrane properties essential to the survival and function of the cell. Populations of erythrocytes display a natural and finite range of sensitivities to osmotic shock that has been directly correlated, in studies from other laboratories, to the presence of spectrin. We used a procedure to isolate subpopulations of 1) the osmotically most sensitive and 2) the osmotically most resistant erythrocyte membranes in an attempt to select for membranes enriched and depleted in spectrin (and/or a related component). The mechanical function of the spectrin-based membrane skeleton was further explored in these two subpopulations by searching for any effect on the time-dependent increase in fusion zone diameter in pairs of electrofused erythrocyte ghosts as a model for cell fusion. The results clearly show that the diameter expansions in fusions of membranes from osmotically resistant erythrocytes are faster in the early stage (up to 9 to 10 s after fusion) but do not thereafter expand as far as in fusions of membranes from osmotically sensitive membranes.
