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 translocation of large proteins through nanopores smaller than their native dimensions opens opportunities to probe endogenous biological processes, assess protein stability, and enable nanopore-based linearization for protein sequencing. Here, we demonstrate that electroosmotic flow (EOF) drives the passage of megadalton proteins through geometric constrained nanopores. Using glass nanopipettes with tip diameters up to 2.5-fold smaller than the proteins, we show that EOF actively captures, aligns, and deforms macromolecules─including immunoglobulin M (IgM) and α
