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
Analyses of mitochondrial sequences revealed the existence of a group I intron in the cytochrome oxidase subunit 1 (cox1) gene in 13 of 41 genera (20 out of 73 species) of corals conventionally assigned to the suborder Faviina. With one exception, phylogenies of the coral cox1 gene and its intron were concordant, suggesting at most two insertions and many subsequent losses. The coral introns were inferred to encode a putative homing endonuclease with a LAGLI-DADG motif as reported for the cox1 group I intron in the sea anemone Metridium senile. However, the coral and sea anemone cox1 group I introns differed in several aspects, such as the intron insertion site and sequence length. The coral cox1 introns most closely resemble the mitochondrial cox1 group I introns of a sponge species, which also has the same insertion site. The coral introns are also more similar to the introns of several fungal species than to that of the sea anemone (although the insertion site differs in the fungi). This suggests either a horizontal transfer between a sponge and a coral or independent transfers from a similar fungal donor (perhaps one with an identical insertion site that has not yet been discovered). The common occurrence of this intron in corals strengthens the evidence for an elevated abundance of group I introns in the mitochondria of anthozoans.
