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

MXenes, a promising class of two-dimensional materials derived from transition metal carbides and nitrides, are attracting considerable attention for their remarkable properties and potential uses in energy storage, EMI shielding, electronics, etc. Modifying surface terminations is essential for tuning the electron structure of MXenes, significantly affecting their properties. However, existing methods for altering the surface chemistry, particularly regarding oxygen termination, encounter significant challenges, such as low substitution efficiency and self-oxidation during treatment, resulting in the absence of pure O-terminated MXenes in the literature. Here, we present a general NaOH/NaI molten salt modification strategy that successfully prepares pure O-terminated MXenes. The effectiveness of this reaction stems from the naked OH ions in the molten salt, along with elevated temperatures that facilitate substitution, all while remaining below the temperatures that cause structural degradation and self-oxidation of MXenes. Consequently, the intrinsic properties of pure O-terminated MXenes undergo significant changes, including continuous tunability of the work function (3.67 to 4.17 eV) and distinct temperature-dependent resistance behavior. In addition, pure O-terminated Ti
