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

Noise, a disturbing and unwanted sound is currently being perceived as a widespread environmental stressor. In the present study we investigated the activation of oxidative stress as a mechanism involved in cognitive impairment through changes in neuro-inflammation. Sprague Dawley rats (200-220 ​ ​g ​m) were exposed to moderate (100dB) sound pressure level (SPL) noise daily for 2 ​h ​s over a period of 15 and 30 days and the consequence on brain regions of hippocampus observed through behavioral studies by Morris Water Maze to assess effects on spatial memory coupled with biochemical evaluation of markers of oxidative stress and inflammation. Further, the underlying mechanism pertaining to apoptosis was investigated by immuno-histological studies through assessment of Caspase-3 and TUNEL assay as well as morphological parameters, namely Nissl bodies in CA1, CA3 and DG regions of hippocampus. Poorer performance in the MWM indicative of decrement in concept formation, attention, working memory, and reference memory was observed on 15 and 30 days of noise exposures. At the cellular level, increased oxidative stress and inflammation was noticed as evinced by elevated levels of TNF-α, IL-6, IL-1α and IFN-γ in both hippocampus and plasma. Exposure to noise also led to a gradual increase in the number of pyknotic and apoptotic neurons together with the increase in DNA fragmentation in hippocampus. Increased levels of inflammatory genes (
