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

Clinical study reports hearing loss in patients with low folic acid (FA) and elevated homocysteine (Hcy). We hypothesize that elevated Hcy induces imbalance in matrix turnover and oxidative stress in cochlea. Cystathione beta-synthase heterozygous knockout mice were used as model for hyperhomocysteinemia. Matrix remodeling induced by Hcy resulted from elevated MMP-2, -9, and -14. MMP-2 and -9 showed elevated gelatinase activity in CBS (+/-) cochlea. Tissue inhibitors of matrix metalloproteinase were significantly lower in CBS (+/-) cochlea. The expression analyses for MMPs and TIMPs were equally represented at protein and mRNA levels. Cochlea of CBS mice showed following structural changes; (1) detachment of tectorial membrane lying on hair cells (2) thinner s. vascularis (3) large fibroblast in spiral ligament. Hcy induced higher protein nitrotyrosination and cytosolic NADPHoxidase subunit p22(phox) in cochlea. It is thus suggested that Hcy induced matrix imbalance, structural changes and oxidative stress in cochlea.
