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 cytoskeletal Filamenting temperature-sensitive Z (FtsZ) ring is critical for cell division in bacteria and chloroplast division in photosynthetic eukaryotes. While bacterial FtsZ rings are composed of a single FtsZ, except in the basal glaucophytes, chloroplast division involves two heteropolymer-forming FtsZ isoforms: FtsZ1 and FtsZ2 in the green lineage and FtsZA and FtsZB in red algae. FtsZ1 and FtsZB probably arose by duplication of the more ancestral FtsZ2 and FtsZA, respectively. We expressed fluorescent fusions of FtsZ from diverse photosynthetic organisms in a heterologous system to compare their intrinsic assembly and dynamic properties. FtsZ2 and FtsZA filaments were morphologically distinct from FtsZ1 and FtsZB filaments. When coexpressed, FtsZ pairs from plants and algae colocalized, consistent with heteropolymerization. Fluorescence recovery after photobleaching experiments demonstrated that subunit exchange was greater from FtsZ1 and FtsZB filaments than from FtsZ2 and FtsZA filaments and that FtsZ1 and FtsZB increased turnover of FtsZ2 and FtsZA, respectively, from heteropolymers. GTPase activity was essential only for turnover of FtsZ2 and FtsZA filaments. Cyanobacterial and glaucophyte FtsZ properties mostly resembled those of FtsZ2 and FtsZA, though the glaucophyte protein exhibited some hybrid features. Our results demonstrate that the more ancestral FtsZ2 and FtsZA have retained functional attributes of their common FtsZ ancestor, while eukaryotic-specific FtsZ1 and FtsZB acquired new but similar dynamic properties, possibly through convergent evolution. Our findings suggest that the evolution of a second FtsZ that could copolymerize with the more ancestral form to enhance FtsZ-ring dynamics may have been essential for plastid evolution in the green and red photosynthetic lineages.
