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

A woman in her 70s was referred for evaluation of a small (8 mm) hepatic nodule detected on magnetic resonance imaging (MRI). The lesion demonstrated high signal intensity on diffusion-weighted imaging (DWI) with low apparent diffusion coefficient (ADC) values, which is atypical for small hepatocellular carcinoma (HCC). Contrast-enhanced ultrasonography (CEUS) revealed washout within 60 s, which is also atypically early for HCC. Histopathological examination confirmed hepatic mucosa-associated lymphoid tissue (MALT) lymphoma. The combination of high signal intensity on DWI, a low ADC value, and early washout on CEUS is particularly useful in identifying small atypical hepatic tumors, such as MALT lymphoma, that mimic HCC.
