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

backgroundAutoantibodies, including anti-nuclear antibodies (ANA), are typically present in autoimmune hepatitis (AIH), but may be detected in other liver conditions, including metabolic dysfunction-associated steatotic liver disease (MASLD), even in the absence of an autoimmune disorder.

aimTo identify predictive factors for the non-confirmation of AIH diagnosis in patients with liver dysfunction of unknown etiology and positive autoantibodies.

methodsA retrospective cohort study was conducted in a university-affiliated hospital, including consecutive adult patients with liver dysfunction of unknown etiology and positive autoantibodies typically present in hepatic autoimmune disorders, who underwent liver biopsy, between June 2016 and August 2023. Patients with other known liver diseases or contraindications to liver biopsy were excluded, as well as those who underwent liver biopsy and had a poor specimen quality.

resultsA total of 81 patients were included, of whom 53.1% were diagnosed with AIH and 46.9% with MASLD. ANA had a high sensitivity (83.7%) in diagnosing AIH but the lowest specificity (18.4%). In patients with ANA positivity, male, diabetic and obese individuals were more likely to have a non-confirmed AIH (

conclusionAIH was not confirmed in 47% of patients with liver dysfunction and positive autoantibodies. Multivariate analysis identified male gender and elevated CAP values as independent predictive factors for a non-confirmed diagnosis of AIH in patients with liver dysfunction and ANA positivity. Further prospective and multicenter validation is required in order to corroborate our findings.
