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 the 20 years since human embryonic stem cells, and subsequently induced pluripotent stem cells, were first described, it has become apparent that during long-term culture these cells (collectively referred to as 'pluripotent stem cells' (PSCs)) can acquire genetic changes, which commonly include gains or losses of particular chromosomal regions, or mutations in certain cancer-associated genes, especially TP53. Such changes raise concerns for the safety of PSC-derived cellular therapies for regenerative medicine. Although acquired genetic changes may not be present in a cell line at the start of a research programme, the low sensitivity of current detection methods means that mutations may be difficult to detect if they arise but are present in only a small proportion of the cells. In this Review, we discuss the types of mutations acquired by human PSCs and the mechanisms that lead to their accumulation. Recent work suggests that the underlying mutation rate in PSCs is low, although they also seem to be particularly susceptible to genomic damage. This apparent contradiction can be reconciled by the observations that, in contrast to somatic cells, PSCs are programmed to die in response to genomic damage, which may reflect the requirements of early embryogenesis. Thus, the common genetic variants that are observed are probably rare events that give the cells with a selective growth advantage.
