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
Coenzymes such as the pyridoxal vitamers promote their native reactions in the absence of enzymes and may therefore have played an early role in the emergence of metabolism. However, it is still unclear whether coenzymes could have been produced nonenzymatically according to their biosynthetic pathways. Here, we show a nonenzymatic analogue of pyridoxal vitamer biosynthesis that occurs in milliseconds when a dilute aqueous solution of ammonia and the triose and pentose phosphates used by the biological pathway is electrosprayed to produce charged droplets exhibiting strong interfacial electric fields. Pyridoxal vitamers were not observed when both sugars lacked phosphoryl groups, suggesting the importance of phosphoryl groups in the enzymatic pathway also extends to analogous nonenzymatic chemistry. Pyridoxal coenzyme biosynthesis joins a growing body of evidence showing that nonenzymatic precursors to metabolic pathways could have initiated in environments containing electric fields of a similar strength to those found in enzymes.
