1 · What the graph read from it

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.

2 · The registry

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

introductionOxidative stress and cytokines play an important role in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). We compared the presence of oxidative stress and cytokines in 25 patients with NAFLD with 25 age, sex and BMI-matched patients with chronic viral hepatitis (CVH) and 25 healthy volunteers (HV). METHODOLOGY: Oxidative stress was studied biochemically by markers of lipid peroxidation and biochemical assessment of anti-oxidant status and various cytokines were studied by ELISA.

resultsPatients with NAFLD had significantly higher levels of malondialdehyde (MDA) (p = 0.000) and conjugated dienes (CD) (p = 0.000) in comparison to HVs. Patients with NAFLD also had significantly higher MDA levels (p = 0.000) in comparison to CVH patients. Patients with NAFLD had significantly lower GSH levels (p = 0.004) in comparison to HVs. Patients with NAFLD had higher GPx activity (p = 0.028) in comparison to HVs. Catalase activity was significantly decreased in both NAFLD (p = 0.001) and CVH patients (p = 0.000) in comparison to HVs. Patients with NAFLD had significantly higher SOD activity (p = 0.000) in comparison to CVH patients. There was no difference in serum levels of IL-1β and TNF-α amongst three groups. Patients with CVH were found to have higher IL-8 serum levels (p = 0.039) in comparison to HVs. CVH patients also had higher TGF-β levels (p = 0.002) in comparison to both NAFLD patients and HVs.

conclusionDifferences in the markers of oxidative stress and anti-oxidant status between NAFLD, CVH and healthy volunteers suggest presence of higher oxidative stress in patients with NAFLD.
