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
Chloroplasts originated from a cyanobacterium, which was engulfed by a primitive eukaryotic host cell. During evolution, chloroplasts have largely lost their autonomy due to the loss of many genes from their own genomes. Consequently, expression of genes encoded in the chloroplast genome is mainly controlled by the factors transferred from the cytosol to chloroplasts. However, chloroplast genomes of glaucophytes and red algae have retained some transcription factors (hypothetical chloroplast open reading frame 27 to 30 [Ycf27-Ycf30]) that are absent from green algae and land plants. Here, we show that the red algal chloroplast up-regulates transcription of the Rubisco operon rbcLS-cbbX via Ycf30 independently of nuclear control. Light-induced transcriptional activation of the Rubisco operon was observed in chloroplasts isolated from the red alga Cyanidioschyzon merolae. The activation was suppressed by 3-(3,4-dichlorophenyl)-1,1-dimethylurea. These results suggest that chloroplast autonomously regulates transcription of the Rubisco operon in response to the activation of photosynthesis driven by the light. Transcriptional activation of the Rubisco operon was specifically repressed by the addition of anti-Ycf30 antibodies. Furthermore, reduced NADP, ribulose-1,5-bisphosphate, and 3-phosphoglyceric acid triggered the up-regulation of Rubisco transcription in the dark, and the activation was dependent on Ycf30. Thus, red algal chloroplasts have retained a nucleus-independent transcriptional regulation of the Rubisco operon to respond to environmental changes. The autonomous system would have been necessary for the initial fixation of cyanobacterial photosynthesis in the ancient nonphotosynthetic eukaryotic host. It has remained functional in the red algal chloroplast over evolutionary time.
