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 46-year-old male with no comorbidities was referred to our hospital because of jaundice and elevated LFT markers. After further investigations, he underwent magnetic resonance cholangiopancreatography (MRCP), which revealed a hypo-enhancing periampullary mass measuring 15 mm in size causing common bile duct (CBD) dilatation of 12 mm in cross diameter with intrahepatic biliary obstruction, which explained the patient's symptoms. Side-view endoscopy was performed to obtain a specimen of the mass. Further histopathological workup revealed poorly differentiated neuroendocrine carcinoma (NEC). A multidisciplinary team (MDT) was conducted, and the patient was planned to undergo positron emission tomography-computed tomography (PET-CT) scan to investigate any further organ metastasis. Unfortunately, the patient missed his upcoming appointments and was lost to follow-up. Nevertheless, more research is needed to understand pathogenesis and the best course of management for small periampullary NETs.
