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

Precise regulation of progenitor identity is essential for the formation of functional auditory circuits. Cochlear nuclei arise from two major progenitor populations: Atoh1-expressing progenitors generate excitatory glutamatergic neurons, while Ptf1a-expressing progenitors generate inhibitory GABAergic and glycinergic neurons. Lmx1a and Lmx1b, expressed in the hindbrain roof plate, maintain Atoh1 expression in lower rhombic lip progenitors that give rise to excitatory neurons of the cochlear nuclei. Detailed analysis using dye tracing of cochlear and vestibular central projections revealed an overall reduction of input in both Lmx1a knockout mice and Lmx1a knockout mice with additonal loss of one copy of Lmx1b, although projections to the dorsal cochlear nucleus (DCN) remain relatively preserved. Dye insertion at the crossing of the acoustic stria demonstrate a progressive loss of the ventral acoustic stria (VAS) and its altered trajectory between the trigeminal and restiform body in Lmx1a
