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 chlorophyll (Chl) a/b proteins of the photosynthetic prokaryotes appear to have evolved by gene duplication and divergence of the core Chl a antenna family, which also includes CP43 and CP47 and the iron-stress induced Chl a-binding IsiA proteins. We show here that Prochlorothrix hollandica has a cluster of three pcb (prochlorophyte chlorophyll b) genes which are co-transcribed. The major antenna polypeptides of 32 and 38 kDa are encoded by pcbA and pcbC respectively. The pcbC gene is significantly divergent from the other two and may have originated by a gene duplication independent of the one that led to isiA and the other prochlorophyte pcb genes. The distant relatedness of the three prochlorophyte genera implies that not only the ability to make Chl b and use it for light-harvesting arose independently in the three lineages, but also that the pcb genes may have arisen as the result of independent gene duplications in each lineage.
