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

In a number of mouse models of hereditary deafness, therapeutic transgene delivery to the cochlea and vestibular organs using adeno-associated viral vectors (AAVs) has shown striking rescue of hearing and balance. However, only a subset of AAV capsids have shown efficacy in transducing both inner hair cells and outer hair cells, and it is also not clear which of these can be translated to treatment of human inner ear. We recently reported efficient transgene expression of a GFP reporter in a non-human primate cochlea, in both inner and outer hair cells, following injection of the AAV9 capsid variant PHP.B via the round window membrane (RWM). However efficiency was poor at a lower dose. To further define the transduction potential of AAV9-PHP.B, we have performed a dosing study in the cynomolgus monkey and assessed vector-encoded GFP expression. Three animals were injected in both ears and four doses were tested. We describe a transmastoid surgical approach needed to access the RWM of this common primate model. We found that AAV9-PHP.B transduced nearly 100% of both IHCs and OHCs, from base to apex, at the higher doses (3.5 × 10
