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

backgroundGenetic and acquired forms of small fiber neuropathies lead to debilitating health conditions, resulting in pain or loss of sensation. These neuropathies are caused by dysfunction or degeneration of unmyelinated peripheral sensory axons: c fibers. Rodent models have been used to investigate molecular mechanisms leading to neuropathies and search for potential therapeutic targets. Although these studies have advanced our understanding of small fiber neuropathies, rodent studies don't fully recapitulate human diseases. Sensory neurons derived from human induced pluripotent stem cells (iPSC) hold promise towards advancing the field of small fiber neuropathies. NEW

methodHere, we report a quick and efficient protocol to generate human sensory neurons from iPSC within ten days.

resultsThe generated neurons expressed generic sensory markers (Brn3A, Islet 1, and neurofilament M) as well as the sensory neuron-associated sodium channel subtypes NaV1.7 and NaV1.8. Additionally, ∼80% of generated sensory neurons were positive for transient receptor potential vanilloid 1 (TRPV-1), a marker for unmyelinated sensory axons. COMPARISON WITH OTHER

methodsPrevious investigators have generated sensory neurons from iPSCs, with a protocol length range of up to 42 days. Most methodologies either employ a small molecule differentiation or an "accelerated" method, whereas our new model is generated by utilizing mRNA.

conclusionThis novel protocol enables rapid generation of human sensory neurons from human iPSCs, achieving 60-70% efficiency. A shorter protocol can improve modeling of small-fiber neuropathies - for example, diabetic peripheral neuropathy and toxic conditions like chemotherapy-induced peripheral neuropathy.
