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.
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
Detection of nucleobases is of great significance in DNA sequencing, which is one of the main goals of the Human Genome Project. The synthesis of Hachimoji DNA, an artificial genetic system with eight nucleotide bases, has induced a transformative shift in genetic research and biosensing. Here, we present a systematic investigation of the adsorption behavior and electronic transport properties of natural and modified DNA bases on a Janus molybdenum sulfur hydride (MoSH) monolayer using density functional theory (DFT) and nonequilibrium Green's function (NEGF) methods. Our results demonstrate that the S side of the MoSH monolayer is more effective as a sensing platform compared to the H side, which undergoes significant structural distortions due to chemisorption. The S side selectively distinguishes natural bases A and T from G and C, and modified bases S and Z from others. However, the negligible changes in current after base adsorption highlight the limitations of relying solely on current sensitivity for detection. Our findings provide valuable insights into the design of MoSH monolayer-based sensing platforms for selective DNA base detection, with potential applications in next-generation DNA sequencing technologies.
