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 protocols described here address methods used in two crucial stages in the retroviral reprogramming of somatic cells to produce human induced pluripotent stem cell (hiPSC) lines. The first is an optimized method for producing lentivirus at an efficiency 600-fold greater than previously published, and it includes conjugation of the lentivirus to streptavidin superparamagnetic particles; this process takes 8 d. The second method enables the isolation of true hiPSCs immediately after somatic cell reprogramming and involves column-based positive selection of cells expressing the pluripotency marker TRA-1-81. This process takes 2 h and, as it is directly compatible with feeder-free culture, the time burden of manually identifying and mechanically propagating hiPSC colonies is reduced drastically. Taken together, these methods accelerate the production of hiPSCs and enable lines to be isolated, expanded to approxiamtely 10⁷ cells and cryopreserved within 6-8 weeks.
