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 generation of induced pluripotent stem cells (iPSCs) devoid of permanently integrated reprogramming factor genes is essential to reduce differentiation biases and artifactual phenotypes. We describe a protocol for the generation of human iPSCs using a single polycistronic lentiviral vector (pLM-fSV2A) coexpressing OCT4, SOX2, KLF4 and c-MYC; this is flanked by two loxP sites in its long terminal repeats (LTRs). Human iPSC lines are established with an efficiency of up to 1% and screened to select single or low vector copy lines. To deal with potential insertional mutagenesis, the vector integrations are then mapped to the human genome. Finally, the vector is excised by transient expression of Cre recombinase (coexpressed with mCherry) through an integrase-deficient lentiviral vector. Vector-excised iPSC lines maintain all characteristics of pluripotency. This protocol can be used to efficiently derive transgene-free iPSCs from many different starting cell types in approximately 12-14 weeks.
