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

Oxidative stress plays an important role in several inner ear diseases and normal aging. Nuclear (erythroid-derived 2)-like 2, also known as Nrf2, is a transcription factor encoded by the NFE2L2 gene that controls the expression of genes necessary to reduce oxidative stress. There are no studies to the date on the localization of Nrf2 in the human inner ear in normal or pathological conditions. Therefore, we investigated the immunohistochemical localization of Nrf2 in the human cochlea and vestibule using formalin-fixed celloidin-embedded human temporal bone sections. Nrf2 immunoreactivity (IR) was found in the inner and outer hair cells and supporting cells of the organ of Corti throughout the cochlea. Nfr2-IR was also found in hair cells and supporting cells of the maculae and cristae vestibular sensory epithelia. Nrf2-IR was decreased in the organ of Corti of older age individuals. The immunolocalization of Nrf2 in both auditory and vestibular sensory epithelia suggest that this transcription factor may play a relevant role in protecting sensory hair cells from oxidative stress.
