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

2D inorganic electrides have attracted extensive interdisciplinary interest due to their unique physicochemical properties, which arise from the presence of non-nuclear-bound interstitial anionic electrons (IAEs). Nevertheless, the stringent design criteria for realizing 2D IAEs have limited viable candidates to only a few categories, thereby constraining the expansion of the candidate pool and further exploration of related applications. Here, based on the electronegativity differences of elements and combined with the design principles of 2D inorganic electrides, we constructed eight negative-valence transition metal-based AB-type 2D inorganic electrides (A = Ca/Sr/Ba, B = Cu/Ag/Au). These materials exhibit a typical layered structure, forming an ordered alternating arrangement of atomic layers and IAE layers along the k
