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
A rhodium-catalyzed reductive carbonylative cyclization for the direct synthesis of 3-silyl-1-indanones from readily available aryl alkynes and hydrosilanes is described. This transformation concurrently introduces a silicon moiety and constructs the indanone core under an atmosphere of carbon monoxide, exhibiting high regioselectivity. The reaction features a broad substrate scope across a range of symmetrical and unsymmetrical alkynes as well as diverse hydrosilanes. Preliminary mechanistic studies support a pathway involving hydrosilylation, rate-limiting C-H activation, and carbonylation. This work provides a concise and practical route to valuable organosilicon scaffolds.
