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

To improve the control and precision in polymer synthesis, the development of polymerization with logical control by multiple stimuli has attracted considerable attention in recent years. Herein, we describe the introduction of a dual regulation by light and pH to organocatalytic atom transfer radical polymerization (O-ATRP), which features mild pH conditions, visible light irradiation, transition metal-free products, and excellent on/off control by both pH and light. 1,1-Binaphthol (BINOL) was successfully identified as a class of pH-responsive photoredox catalysts for O-ATRP, and show readily tunable photophysical properties and highly reversible chromic shift of maximum absorption (up to 60 nm) by very mild pH-mediation (pH 5/7). Moreover, the unique pH-responsive feature of BINOL also inspires the discovery of simple phenols like naphthol and pyrenol that could also drive the radical polymerization under light and afford higher catalytic efficiency and better control upon basic mediation. Given the widespread presence of phenols in natural compounds, we anticipate this work could also draw greater attention to their potential pH-responsive photophysical properties or other roles in catalysis or life systems.
