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
introductionIschemia-reperfusion (I/R) injury, resulting from blood flow interruption and its subsequent restoration, is a prevalent complication in liver surgery. The liver, as a crucial organ for carbohydrate and lipid metabolism, exhibits decreased tolerance to hepatic I/R in patients with diabetes mellitus (DM), resulting in a significant increase in hepatic dysfunction following surgery. This may be attributed to elevated oxidative stress and inflammation. Our prior research established sinomenine's (SIN) protective role against hepatic I/R injury. Nevertheless, the impact of SIN on hepatic I/R injury in DM rats remains unexplored. OBJECTIVE AND
methodsThis study aimed to investigate the therapeutic potential of SIN in hepatic I/R injury in DM rats and elucidate its mechanism. Diabetic and hepatic I/R injury models were established in rats through high-fat/sugar diet, streptozotocin injection, and hepatic blood flow occlusion. Liver function, oxidative stress, inflammatory reaction, histopathology, and Nrf-2/HO-1 signaling pathway were evaluated by using UV spectrophotometry, biochemical assays, enzyme-linked immunosorbent assay, hematoxylin-eosin staining, and Western blot analysis.
resultsHigh-dose SIN (300 mg/kg) significantly attenuated hepatic I/R injury in DM rats, reducing serum activities of ALT and AST, decreasing the AST/ALT ratio, enhancing tissue contents of SOD and GSH-Px, suppressing the levels of TNF-α and IL-6, improving the liver histopathology, and activating Nrf-2/HO-1 signaling by promoting Nrf-2 trans-location from cytoplasm to nucleus. Low-dose SIN (100 mg/kg) was ineffective.
conclusionsThis study demonstrates that high-dose sinomenine's mitigates hepatic I/R-induced inflammation and oxidative stress in diabetes mellitus (DM) rats via Nrf-2/HO-1 activation, suggesting its potential as a preventive strategy for hepatic I/R injury in DM patients.
