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

Mucosal hyperplasia is common sequela of otitis media (OM), leading to the secretion of mucus and the recruitment of leukocytes. However, the pathogenic mechanisms underlying hyperplasia are not well defined. Here, we investigated the role of the AKT pathway in the development of middle mucosal hyperplasia using in vitro mucosal explants cultures and an in vivo rat model. The Akt inhibitor MK2206 treatment inhibited the growth of middle ear mucosal explants in a dose-dependent manner. In vivo, MK2206 also reduced mucosal hyperplasia. Unexpectedly, while PTEN is generally thought to act in opposition to AKT, the PTEN inhibitor BPV reduced mucosal explant growth in vitro. The results indicate that both AKT and PTEN are mediators of mucosal growth during OM, and could be potential therapeutic targets.
