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

This study investigated the effects of intranasal administration of a semaphorin 3A inhibitor (Sema3A-I) in a mouse model of olfactory disorder, where olfactory sensory neuron (OSN) axons had been severely damaged. We performed axotomy (transection of OSN axons) of the OSNs in mice and administered Sema3A‑I intranasally to seven mice and saline to another seven mice. Following treatment, we assessed the thickness of the olfactory epithelium and the regeneration ratio of OSN axons. Intranasal administration of Sema3A-I did not significantly promote OSN regeneration, axonal outgrowth, or improve axonal projection compared to saline administration. Although Sema3A-I administration showed some promotion of axonal outgrowth, the difference was not statistically significant. Continuous subcutaneous administration of Sema3A-I in rats after axotomy promotes OSN regeneration and axonal outgrowth. Given that intranasal administration is minimally invasive, we believe that it may still be a feasible route when combined with additional treatment strategies. Further investigation into administration methods and therapeutic combinations is warranted.
