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

Inner ear organoids derived from pluripotent stem cells could be a useful model system to study development, disease, and regeneration. However, there is considerable heterogeneity in the size, morphology, and efficiency of organoid production using standard protocols. Greater control of the culture microenvironment could decrease heterogeneity and increase the yield of organoids. Animal-derived otic vesicles show some autonomy during development and can differentiate into cochlear and vestibular domains in mesenchyme-free ex vivo culture. Therefore, we investigated whether stem cell-derived otic vesicles can autonomously generate inner ear organoids. Isolated, stem cell-derived vesicles grew into cyst-like organoids with high efficiency, over 90%, when embedded in droplets of the basement membrane matrix Matrigel. Though nearly all vesicles within the aggregate were competent to mature into organoids, the efficiency of organoid production depended on the stage of vesicle isolation and required supplementation with Matrigel.
