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
Gelsolin plays an important role in the regulation of amyloid beta-protein fibrillogenesis. We report here that calcium ionophore A23187 induces the expression of cytoplasmic gelsolin (c-gelsolin), and that protein kinase C (PKC) is involved in the up-regulation of c-gelsolin. In the presence of calcium, both SH-SY5Y and HEK-293 cells upon treatment with A23187 showed an increase in c-gelsolin expression in a concentration-dependent manner. Calcium-mediated up-regulation of c-gelsolin was inhibited by cycloheximide (a general inhibitor of protein synthesis). When cells were pretreated with staurosporine (an inhibitor of a variety of protein kinases including PKC), the up-regulation of c-gelsolin induced by A23187 was inhibited. Calphostin C, an inhibitor of PKC, blocked the up-regulation of c-gelsolin induced by A23187, while inhibitors of mitogen-activated protein kinases had no effect on c-gelsolin expression. In addition, phorbol-12-myristate-13-acetate, an activator of PKC, up-regulated c-gelsolin expression. These results suggest that calcium mediates up-regulation of c-gelsolin in a PKC-dependent manner.
