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

Induced pluripotent stem (iPS) cells may be of use in regenerative medicine. However, the low efficiency of reprogramming is a major impediment to the generation of patient-specific iPS cell lines. Here we report the first selection system for the isolation of human iPS cells. We developed the EOS (Early Transposon promoter and Oct-4 (Pou5f1) and Sox2 enhancers) lentiviral vector to specifically express in mouse and human embryonic stem cells but not in primary fibroblasts. The bicistronic EOS vector marked emerging mouse and human iPS cell colonies with EGFP, and we used puromycin selection to aid the isolation of iPS cell lines that expressed endogenous pluripotency markers. These lines differentiated into cell types from all three germ layers. Reporter expression was extinguished upon differentiation and therefore monitored the residual pluripotent cells that form teratomas. Finally, we used EOS selection to establish Rett syndrome-specific mouse and human iPS cell lines with known mutations in MECP2.
