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

contextThe isomerization of substituted cyclopentadienyl systems plays an important role in understanding substituent effects on sigmatropic rearrangements and proton transfer processes. In this work, R- and proton-shifts in substituted cyclopentadienes (MeCp, tBuCp, SiMe

methodsAll calculations were performed using the Gaussian 16 software package. Geometry optimizations and energy calculations were carried out at the ωB97X-D/6-311+G(d,p) level of theory. Solvent effects (toluene, acetone, nitromethane) were included using the PCM model. Transition states were located using the QST2 method and verified by frequency analysis and intrinsic reaction coordinate (IRC) calculations. Topological analyses of the electron localization function (ELF) were performed with TopMod 09 along the IRC, forming the basis for Bond Evolution Theory (BET) analysis. QTAIM analyses were conducted using the Multiwfn program.
