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 development of hybrid materials combining functional polymers with nanostructured metals has gained significant attention for environmental and sensing applications. In this study, we present a proof-of-concept demonstration of the first-ever binding of a nanosponge polymer (NS) to nanoporous gold (NPG). The polymer was functionalized with a biodegradable lipoic acid linker, allowing efficient attachment to gold surfaces via sulfide bonds. To achieve successful binding, reducing agents were required during NS synthesis to generate free thiol (-SH) groups. Two synthesis approaches were tested, and optimal binding was confirmed with a polymer-to-surface ratio of 1.1 × 10
