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

The BTBR T+ Itpr3tf/J (BTBR) strain is a widely used model of neurodevelopmental disorders, characterized by an altered neuroanatomy, including a full-penetrant agenesis of the corpus callosum. While the adult BTBR brain has been studied thoroughly, less is known about how its brain develops prenatally and about when neurodevelopmental trajectories begin to differ from neurotypical strains. Here, we conducted a comparative histological analysis of fetal brain development across multiple developmental stages in BTBR and C57BL/6J (B6) mice, focusing on neocortical and midline development. BTBR mice showed lower fetal weight but comparable somite counts (assessed at 12.5 days post coitum, dpc) compared to B6 controls, indicating similar developmental timing. Neocortical layering showed a reduced ventricular zone fraction in BTBR fetuses at 15.5 dpc, without a change in overall cortical thickness. Concurrently, midline cell populations immunoreactive for the glutamate aspartate transporter (GLAST) failed to undergo remodeling in subsequent stages, resulting in the failure to form a GLAST+ indusium griseum and the lack of callosal projections crossing the midline at 17.5 dpc, which instead develop normally in B6 fetuses. These findings offer structural correlates for the early neuropathology of the BTBR brain.
