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

The detailed mechanism of reprogramming somatic cells into induced pluripotent stem cells (iPSCs) remains largely unknown. Partially reprogrammed iPSCs are informative and useful for understanding the mechanism of reprogramming but remain technically difficult to generate in a predictable and reproducible manner. Using replication-defective and persistent Sendai virus (SeVdp) vectors, we analyzed the effect of decreasing the expression levels of OCT4, SOX2, KLF4, and c-MYC and found that low KLF4 expression reproducibly gives rise to a homogeneous population of partially reprogrammed iPSCs. Upregulation of KLF4 allows these cells to resume reprogramming, indicating that they are paused iPSCs that remain on the path toward pluripotency. Paused iPSCs with different KLF4 expression levels remain at distinct intermediate stages of reprogramming. This SeVdp-based stage-specific reprogramming system (3S reprogramming system) is applicable for both mouse and human somatic cells and will facilitate the mechanistic analysis of reprogramming.
