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 spatial organization of viral and cellular proteins shapes signal transduction. Here, we present a protocol to quantify differential protein-protein interactions by measuring their spatial association using proximity ligation assays (PLAs). We describe steps for seeding, transfection, proximity labeling, and confocal microscopy imaging and provide procedures for quantitative analysis. Our approach complements co-immunoprecipitation-based interactome data by enabling in situ quantification of differential binding between cellular and viral interaction partners. For complete details on the use and execution of this protocol, please refer to Klute et al.
