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

Wallerian degeneration (WD) is a process of axonal degradation that occurs downstream from a primary injury site and is often seen after strokes affecting the brainstem. This case report documents WD of the bilateral middle cerebellar peduncles (MCPs) in an 81-year-old woman following chronic left paramedian pontine infarction (PPI). An ischemic stroke affecting the pons can trigger downstream axonal degeneration, known as Wallerian degeneration, which involves the structural breakdown of axons distal to the injury site. In this patient, magnetic resonance imaging (MRI) revealed symmetrically increased T2 signal intensity in the MCPs, indicative of WD associated with a known PPI. Although uncommon, it is essential to recognize WD in this location to distinguish it from new ischemic lesions. While the WD of MCPs has not been strongly linked to specific deficits, this phenomenon advances our understanding of the secondary effects of pontine strokes (PS). Detailed documentation of such cases helps improve diagnostic accuracy and prevents misinterpretation of expected postinfarct changes in neuroimaging. This report provides a valuable example of increasing awareness of WD involving MCPs due to PPI.
