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.
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 three-component elemento-boration of alkynes using a borane and a nucleophile is a highly efficient method to generate complex alkenyl-boranes. Benzoxaborinines are a class of alkenyl boranes of considerable importance, including in the fight against antibiotic resistance. However, a three-component elemento-boration process to form functionalised benzoxaborinines was an unmet challenge before this work. Herein, we report operationally simple three-component thio- and carbo-boration reactions to form functionalised benzoxaborinines using commercially available reagents. The processes also were applicable to form functionalised benzazaborinines, which are of interest as naphthalene bioisosteres. The nucleophile scope included thioethers, thiols, and (hetero)arenes. In contrast, when using amine nucleophiles, alkyne hydroamination occurred to form boranils. Mechanistic studies revealed a disparity between thioboration using thioethers and using thiols. While thioethers are effective nucleophiles in their own right, when using thiols the in situ formation of tri-thioboranes ((RS)
