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

Appropriate transmission of sensory afferent input from the peripheral nervous system to spinal locomotor circuits is crucial for efficient and adaptive locomotion. This is partly mediated by spinal interneurons (INs) that regulate afferent input relayed to locomotor networks. After a spinal cord injury (SCI), sensory afferent feedback becomes critical for motor recovery, however these pathways undergo plasticity. Previously, we observed a loss in the inhibitory sensory afferent pathway to locomotor rhythm generating Shox2 INs after SCI. Importantly, the inhibitory INs within sensory afferent pathways to Shox2 INs have yet to be defined. Thus, the goal of the present study was to identify inhibitory INs interposed between sensory afferents and Shox2 INs in the uninjured mouse. Using electrophysiology and pharmacology to test for connectivity, we demonstrate that lumbar inhibitory INs within sensory afferent pathways to Shox2 INs are glycinergic (GlyT2) INs in the medial deep dorsal horn. Afferent stimulation evoked currents in medial deep dorsal GlyT2 INs that were mostly from excitatory, putative monosynaptic connections. Consistent with the electrophysiology, parvalbumin
