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

Photochemically triggered control of keto-enol equilibria is of growing importance in rational synthetic strategies. Questions exist, however, about the extent to which the electrostatic effects (i.e., interactions with counterions and solvent) can perturb or direct such photocatalytic approaches. Here, we directly address the question of whether electrostatic tuning via alkali metal binding can affect the photochemistry of the classic β-diketone molecule, avobenzone, which exists in keto and enol forms. A combination of photodissociation mass spectrometry over the ultraviolet (UV) (390-238 nm) and infrared (IR) (800-1800 cm
