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

In biological and biomedical research, the focus progressively moves towards difficult human proteins, which often can only be expressed in higher eukaryotic cells. Nuclear magnetic resonance (NMR) could contribute significantly to the understanding of important proteins as it is one of the most information-rich methods. However, to exploit the full potential of NMR, proteins must be isotope labeled. Although expression protocols in, for example, HEK293 cells are often established, isotope labeling is difficult and very expensive, and published protocols are mostly limited to adherent cells in plates. To resolve this disparity, we have developed a comprehensive suite of protocols for isotope labeling in HEK293 cells in suspension. We demonstrate uniform
