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 human genome contains thousands of potentially coding short open reading frames (sORFs). While a growing set of microproteins translated from these sORFs have been demonstrated to mediate important cellular functions, the majority remains uncharacterized. In our study, we performed a high-throughput CRISPR-Cas9 knock-out screen targeting 11,776 sORFs to identify microproteins essential for cancer cell line growth. We show that the
