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
Xenopus laevis tadpoles can regenerate whole tails after amputation. We have previously reported that interleukin 11 (il11) is required for tail regeneration. In this study, we have screened for genes that support tail regeneration under Il11 signaling in a certain cell type and have identified the previously uncharacterized genes Xetrov90002578m.L and Xetrov90002579m.S [referred to hereafter as regeneration factors expressed on myeloid.L (rfem.L) and rfem.S]. Knockdown (KD) of rfem.L and rfem.S causes defects of tail regeneration, indicating that rfem.L and/or rfem.S are required for tail regeneration. Single-cell RNA sequencing (scRNA-seq) revealed that rfem.L and rfem.S are expressed in a subset of leukocytes with a macrophage-like gene expression profile. KD of colony-stimulating factor 1 (csf1), which is essential for macrophage differentiation and survival, reduced rfem.L and rfem.S expression levels and the number of rfem.L- and rfem.S-expressing cells in the regeneration bud. Furthermore, forced expression of rfem.L under control of the mpeg1 promoter, which drives rfem.L in macrophage-like cells, rescues rfem.L and rfem.S KD-induced tail regeneration defects. Our findings suggest that rfem.L or rfem.S expression in macrophage-like cells is required for tail regeneration.
