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

This paper describes a detailed protocol for human pluripotent stem cells (hPSCs) cultivation as matrix-free cell-only aggregates in defined and xeno-free culture medium in stirred tank bioreactors (STBRs). Starting with a frozen stock pre-expanded on conventional culture dishes (2D), the ultimate process is performed in 150 mL culture scale in stirred tank bioreactors (3D) and is designed to produce up to 500 million pluripotent hPSC within 7 days. The culture strategy includes perfusion-based cell feeding facilitating process control, automation, and higher cell yields. Ultimately, this detailed protocol describes an important step for generating a defined starting cell population for directed lineage differentiation and subsequently fueling human cell-based assays and regenerative medicine approaches.
