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

Confining polyiodide species at the cathode is pivotal to the stability and long life of aqueous zinc-iodine batteries (AZIBs). Current approaches using porous inorganic materials to physically trap polyiodide species or organic additives to electrostatically bind them remain ineffective due to size mismatches or weak ionic interactions. Here, we introduce a host-guest strategy to cage polyhalides while enabling their transport between niches within a cross-linked polycyclodextrin (polyCD) network. Experimental and computational results indicate that the polymer derived from β-CD exhibits a moderate binding affinity to polyhalide anions, attributable to its appropriate inner diameter and hydrophobic cavity. For our poly(β-CD)/KI
