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

purposeTo retrospectively evaluate magnetic resonance images acquired from rats subjected to a murine model of extraparenchymal neurocysticercosis.

methodsThe model consisted of injecting 50 Taenia crassiceps cysticerci into the cisterna magna of Wistar rats. To validate disease induction, magnetic resonance imaging was performed, focusing on the assessment of hydrocephalus and cysts distribution throughout the cerebrospinal fluid compartments. Ventricular dilation was quantified using the frontal horn ratio (FHR), calculated by dividing the maximal width of the frontal horns by the inner-table internal diameter.

resultsIntracranial abnormalities were found 63.0% of the animals, predominantly ventricular dilation (> 90%), mainly involving the lateral ventricles. The most affected compartments were the cisterna magna (85.2%) and supratentorial basal cisterns (78.8%). Cysts were identified in the cerebral convexity in 10.6% of cases and in the subcutaneous tissue in 39.2% of infected animals. The mean FHR was 0.62 ± 0.13. Higher FHR values were associated with the presence of cysts in the CSF, but not in the subcutaneous tissue (p = 0.743).

conclusionThe translational relevance of this extraparenchymal NCC model is underscored by neuroimaging findings that closely resemble the human condition, providing a valuable platform for future mechanistic studies on pathogenesis and treatment development.
