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

Anti-mitochondrial M2 antibody (AMA-M2) is specific to primary biliary cirrhosis (PBC), but can also be found in certain patients with autoimmune hepatitis (AIH). Effective methods of differentiating between PBC and AIH are required, as their clinical course and management are different. Titers of AMA-M2 were analyzed before and after follow-up in patients with PBC or AIH. Patients who underwent liver biopsy and were diagnosed with either AIH (10 patients) or PBC (3 patients) were enrolled in the study. The AMA-M2 antibody titers of these patients were analyzed upon hospital admission. AMA-M2 reacted with the pyruvate dehydrogenase complex-E2, branched-chain 2-oxo acid dehydrogenase complex and 2-oxoglutaric acid dehydrogenase complex in the assay utilized for this study. The cut-off value for AMA-M2 was 5. Six AIH patients were AMA-M2(-) and 4 were AMA-M2(+). The titer for the AIH patients who were AMA-M2(+) was 24.8±14.8, compared with 324±174 in the patients with PBC (P=0.0138). Three AMA-M2(+) AIH patients were followed-up after liver biopsy. The AMA-M2 levels had decreased in all 3 patients, becoming undetectable in 2 of them. In conclusion, certain patients with AIH in this study were found to be AMA-M2(+), but the titers were significantly lower than those in the patients with PBC. At follow-up, the AIH patients exhibited decreased AMA-M2 titers.
