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
purposeThe aim of this study was to explore how sulforaphane (SFN), a well-known nuclear factor erythroid 2-related factor 2 (Nrf2) pathway activator, regulates hepatic autophagy and apoptosis by modulating the polarization of Kupffer cells via the Nrf2/HO-1 pathway in a hemorrhagic shock/resuscitation (HS/R) model in mice.
methodsMale c57/BL6 mice were subjected to hemorrhagic shock (HS) for 90 min under blood pressure control. Resuscitation was performed by reinfusing the withdrawn blood and infusing 0.9% NaCl, and SFN was administered intraperitoneally. All animals were euthanized 24 h after resuscitation, and liver tissue samples were collected for TUNEL staining, western blot analysis, immunohistochemical staining, immunofluorescence staining, and observation using transmission electron microscopy (TEM). Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) was performed to verify the SFN distribution in the liver.
resultsSFN reached the liver within the first hour after it was injected. SFN was found to promote the hepatic Nrf2/HO-1 pathway and the polarization of Kupffer cells to the M2 phenotype rather than the M1 phenotype after HS/R. Furthermore, SFN inhibited hepatic apoptosis after HS/R, as demonstrated by a decrease in the Bax/Bcl-2 ratio, fewer TUNEL-positive cells, and changes in cleaved caspase 3 expression. Enhanced hepatic autophagy was observed after HS/R, as shown by an increase in the number of autophagosomes, a higher LC3-II/LC3-I ratio, and decreased expression of p62 and beclin-1.
conclusionsIn this study, SFN administration inhibited hepatic apoptosis and promoted hepatic autophagy by inducing Kupffer cells to polarize to the M2 phenotype rather than the M1 phenotype via the Nrf2/HO-1 pathway.
