Limits to shortening in smooth muscle tissues.
Article in Journal of muscle research and cell motility, 1992. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The extent of shortening in smooth muscle tissues is limited by a number of internal and external factors. In this study, continuous measurements of the stiffness of active muscle were made to characterize the mechanical forces acting to limit shortening. Rabbit ovarian ligament and mesotubarium superius muscles were allowed to shorten as far as possible under light afterloads; under these conditions a stiffness increase was observed that was closely related to the instantaneous muscle length and that was unaffected by other factors influencing the degree of shortening (afterload, time and intensity of activation, temperature, etc.). The results are considered in terms of a hypothesis relating the tissue-based constraints on radial expansion at short lengths to an additional load on the contractile apparatus, an internal force that is externally manifested as an increase in axial stiffness. Changing the cellular volume by varying the tonicity of the bathing medium provided tentative confirmation of the hypothesis.
