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

The formation of lactones via radical-mediated C─C bond formation is a powerful but overlooked method, especially given recent interest in the conversion of alcohols to radical intermediates using photochemistry. Building on our previous work with cobalt porphyrin complexes, a carbonylation-homolysis process is described for complex unsaturated alcohols and a simple benzylic model system, leading to the production of saturated or unsaturated products. Ligands and additives are demonstrated to promote either reductive or oxidative termination, leading to divergent reactivity in different contexts. The role of cobalt hydride intermediates is also discussed, as well as the application of this strategy toward the synthesis of a lactone-containing limonoid natural product.
