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

Understanding spin state changes and their influence on the reactivity of earth-abundant transition metal complexes is essential for unlocking the full potential of these elements. While precedented in biological contexts and related model complexes, control of metal spin state is underexplored as a mode for reactivity control in organometallic chemistry. Here we describe coordination-induced spin modulation as a strategy to overcome spin blocking to enable C-H functionalization with four-coordinate high-spin iron(II) dimethyl complexes. Addition of monodentate phosphines induced room-temperature C-H methylation of arenes, while evaluation of sterics and σ-donacity demonstrated PhPMe
