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

article highlightsIER3IP1 mutations are linked to the development of microcephaly, epilepsy, and early-onset diabetes syndrome 1. However, the underlying molecular mechanisms of cell dysfunction are unknown. Using targeted genome editing, we generated specific IER3IP1 mutations in human embryonic stem cell lines that were differentiated into pancreatic islet lineages. Loss of IER3IP1 resulted in a threefold reduction in endoplasmic reticulum-to-Golgi trafficking of proinsulin in stem cell-derived β-cells, leading to β-cell dysfunction both in vitro and in vivo. Loss of IER3IP1 also triggered increased markers of endoplasmic reticulum stress, indicating the pivotal role of the endoplasmic reticulum-to-Golgi trafficking pathway for β-cell homeostasis and function.
