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
Intracerebral hemorrhage (ICH) is an incurable neurological disease. Microglia activation and its related inflammation contribute to ICH-associated brain damage. FERM domain containing kindlin 1 (FERMT1) is an integrin-binding protein that participates in microglia-associated inflammation, but its role in ICH is unclear. An ICH model was constructed by injecting 50 µl of autologous blood into the bregma of rats. FERMT1 siRNA was injected into the right ventricle of the rat for knockdown of FERMT1. A significant striatal hematoma was observed in ICH rats. FERMT1 knockdown reduced the water content of brain tissue, alleviated brain hematoma and improved behavioral function in ICH rats. FERMT1 knockdown reduced microglia activity, inhibited NLR family pyrin domain containing 3 (NLRP3) inflammasome activity and decreased the expression of inflammatory factors including IL-1β and IL-18 in the peri-hematoma tissues. BV2 microglial cells were transfected with FERMT1 siRNA and incubated with 60 µM Hemin for 24 h. Activation of NLRP3 inflammasome induced by hemin were reduced in microglia when FERMT1 was knocked down, leading to decreased production of inflammatory factors IL-1β and IL-18. In addition, knockdown of FERMT1 prevented the activation of nuclear factor kappa B (NF-κB) signaling pathway in vivo and in vitro. Our findings suggested that down-regulation of FERMT1 attenuated microglial inflammation and brain damage induced by ICH via NLRP3/NF-κB pathway. FERMT1 is a key regulator of inflammatory damage in rats after ICH.
