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
Changes in cell water content resulting from sorbitol addition to the environment of L-929 cells were evaluated gravimetrically using 14C-labeled polyethylene glycol as a probe of extracellular space. Reductions in cell water were proportional to sorbitol supplements up to 0.6 molal, above which no further measurable decrease occurred. No volume regulation occurred for at least 1 h but the percentage of cell water lost was quickly regained when physiological conditions were restored. The amount of cell water lost because of a given hyperosmotic exposure was found to exceed the loss of cell volume. That discrepancy could be the result of an overestimation of extracellular space and/or an underestimation of cell volume reduction as a result of in-folding of the cell surface. Na+ and K+ were also measured in cells of variable water content and volume: no significant change occurred in the amounts of these ions per cell, but large increases in total cell concentration resulted from hyperosmotic exposure. The sum of Na+ and K+ concentrations exceeds the total osmotic pressure of the medium indicating that an appreciable fraction of Na+ and K+ must be bound to fixed charges within the cells. The results are evaluated in the context of intracellular organization.
