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

By enabling the simultaneous engagement of two distinct targets, bispecific antibodies broaden the potential utility of antibody-based therapies. However, bispecific-antibody design and production remain challenging, owing to the need to incorporate two distinct heavy and light chain pairs while maintaining natural nonimmunogenic antibody architecture. Here we present a bispecific-antibody production strategy that relies on co-culture of two bacterial strains, each expressing a half-antibody. Using this approach, we produce 28 unique bispecific antibodies. A bispecific antibody against the receptor tyrosine kinases MET and EGFR binds both targets monovalently, inhibits their signaling, and suppresses MET and EGFR-driven cell and tumor growth. Our strategy allows rapid generation of bispecific antibodies from any two existing antibodies and yields milligram to gram quantities of bispecific antibodies sufficient for a wide range of discovery and preclinical applications.
