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 evaluate morphometric correlation between the interventricular foramen and pars opercularis through MRI.

methodsThis retrospective, cross-sectional, and observational study analyzed 90 cerebral hemispheres from patients treated at Ophir Loyola Hospital. Volumetric T1-weighted MRI sequences (1-mm slices) were processed in 3D Slicer. Distances between the interventricular foramen and pars opercularis were measured along the X (anteroposterior), Y (superoinferior), and Z (laterolateral) axes. Pearson’s correlation and t-tests were applied for statistical analysis.

resultsThe Pars Opercularis was predominantly anterior (9.96 mm) and superior (2.62 mm) to the interventricular foramen, with a mean linear distance of 45.21 mm. Significant lateral differences were observed: the right hemisphere exhibited a greater linear distance (46.52 mm) than the left (43.90 mm). Age did not demonstrate a statistically significant correlation with the laterolateral dimension (Z-axis) or other measured variables.

conclusionThe Interventricular Foramen maintains a consistent spatial relationship with the pars opercularis, with stable positioning and subtle hemispheric differences. These findings refine anatomical knowledge and contribute to neurosurgical planning, particularly in procedures requiring precise anatomical references, such as ventricular surgeries and resections near eloquent cortical areas.
