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

purposeA non-bifurcating cervical carotid artery (NBCCA) is a rare anomaly. Hypoplasia of the internal carotid artery (ICA) is also rare. To the best of our knowledge, their simultaneous coexistence has not been previously reported.

methodsWe report a case of NBCCA associated with ipsilateral ICA hypoplasia diagnosed by magnetic resonance angiography (MRA).

resultsA 52-year-old woman was transported to our hospital by ambulance with severe headache. Magnetic resonance imaging revealed a large suprasellar mass. MRA showed impaired delineation of the right ICA and a 2-mm left ICA aneurysm. Extracranial MRA revealed a right NBCCA. Computed tomography showed a narrow right carotid canal. Right NBCCA concomitant with congenital hypoplasia of the ipsilateral ICA was diagnosed.

conclusionCareful imaging assessment is important to identify these rare anatomical variants and associated aneurysms on the collateral pathway. Awareness of such variations is important in clinical practice, particularly for imaging interpretation and procedural planning.
