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

contextPhenylsilane is an organosilicon molecule containing a silyl group attached to a benzene ring and is widely used as a hydrogen source in organic transformations such as the Mukaiyama hydration reaction. Understanding how external electric fields influence its structural and spectroscopic properties is important for clarifying field-induced molecular behavior. In this work, the effects of external electric fields on the C-C and Si-C bond lengths, total energy, infrared (IR) spectrum, Raman spectrum, UV-vis absorption spectrum, and bond dissociation energy of phenylsilane are investigated. The results show that increasing the electric field strength induces redshifts in several vibrational absorption peaks, including a shift of up to 250 cm

methodsAll calculations were performed using density functional theory (DFT) at the B3LYP/6-31+G(d) level of theory. Geometry optimizations and vibrational frequency analyses were carried out under different external electric field strengths. Infrared and Raman spectra as well as UV-vis absorption spectra were obtained based on the optimized molecular structures. All quantum chemical calculations were performed using the Gaussian 16W software package.
