Involvement of caldesmon at the actin-myosin interface.
Article in The Biochemical journal, 1992. 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
Addition of myosin subfragment 1 (S-1) to the actin-caldesmon binary complex, which forms bundles of actin filaments resulted in the formation of actin/caldesmon-decorated filaments [Harricane, Bonet-Kerrache, Cavadore & Mornet (1991) Eur. J. Biochem. 196, 219-224]. The present data provide further evidence that caldesmon and S-1 compete for a common actin-binding region and demonstrate that a change occurs in the actin-myosin interface induced by caldesmon. S-1 digested by trypsin, which has an actin affinity 100-fold weaker than that of native S-1, was efficiently removed from actin by caldesmon, but not completely dissociated. This particular ternary complex was stabilized by chemical cross-linking with carbodi-imide, which does not have any spacer arm, and revealed contact interfaces between the different protein components. Cross-linking experiments showed that the presence of caldesmon had no effect on stabilization of actin-(20 kDa domain), whereas the actin-(50 kDa domain) covalent association was significantly decreased, to the point of being virtually abolished.
