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
LRP6 is a Wnt coreceptor and plays a key role in Wnt signal transduction. However, the molecular mechanism of LRP6 action in the Wnt signaling cascade has not been fully elucidated. In this study, a small molecule compound SLD1121 is synthesized and identified as a novel agonist of the Wnt/β-catenin signaling pathway. Our results showed that SLD1121 could enhance Wnt signaling through targeting LRP6. SLD1121 interacted with the intracellular domain of LRP6, stabilized LRP6, and accelerated its nuclear translocation. Moreover, SLD1121 promoted the association of LRP6 with β-catenin, or TCF4 or LEF1 in the nucleus, resulting in the expression of Wnt regulatory genes and stemness-associated genes. In a hair regeneration model of C57BL/6J mice, SLD1121 induced the transition of hair follicles from the telogen to anagen phase in the mouse hair growth cycle through the activation of Wnt/β-catenin signaling, resulting in enhanced hair growth of mice. Collectively, our results provide a novel insight into the molecular mechanism for the LRP6-mediated Wnt signaling cascade. By targeting LRP6, SLD1121 has the potential to be used as a therapeutic agent for alopecia.
