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

Initial exposure to a rapidly evolving virus establishes B cell memory that biases later responses to antigenically drifted strains. This "immune imprinting" implies that subsequent exposure to a drifted strain can induce affinity maturation of memory B cells toward cross-reactivity with the drifted strain and hence toward greater overall breadth. Here, we used deep mutational scanning of H1 influenza hemagglutinins (HAs) to investigate how viruses evolve in response to these broad antibody response. We identified escape mutations from clonal antibody lineages that targeted the receptor binding site and lateral patch. By adjusting the antigen-antibody contacts, antibody affinity maturation restricted the potential escape routes for the eliciting strain. However, escape occurred readily in drifted strains. We attribute this escape-prone property of the drifted strains to epistatic networks within HA. Our data explain how the influenza virus continues to evolve in the human population by escaping even broad antibody responses.
