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
Аims: This research aimed to study the features of gene regulation of the inflammatory response in cells carrying mitochondrial mutations associated with atherosclerosis.
backgroundInflammation plays an important, if not decisive, role in the occurrence of atherosclerotic lesions and then accompanies it throughout its further development. Thus, atherogenesis is a chronic inflammatory process. Chronification of inflammation is a consequence of disruption of the normal inflammatory response at the cell level of the vascular wall.
objectivesIn this study, we used cytoplasmic hybrids or cybrids carrying atherosclerosis- associated mitochondrial mutations to study gene regulation of inflammatory response. The main goal of the study was to identify the key genes responsible for the impaired inflammatory response revealed for some cybrids.
methodsInflammatory stimulation of cybrids was induced with bacterial lipopolysaccharide, and assessed through secretion of pro-inflammatory cytokines CCL2, IL8, IL6, IL1b. A transcriptome analysis was performed to identify the key genes (master regulators) in the normal (tolerant) and intolerant response of cybrid cells.
resultsNormal inflammatory response after re-stimulation elicited a much smaller secretion of pro-inflammatory cytokines. In an intolerant response, the level of secretion upon re-stimulation was the same or even higher than after the first stimulation. Normal and intolerant responses differed significantly both in terms of the number of signaling pathways involved and qualitatively, since the signaling pathways for normal and intolerant responses are completely different. Master regulators controlling normal and intolerant inflammatory response were identified. For a normal response to the first inflammatory stimulation, no common master up-regulators and 3 master down-regulators were identified. The reverse situation was observed with the intolerant inflammatory response: 6 master up-regulators, and no master down regulators were identified. After the second inflammatory stimulation, no master regulator common to all studied cytokines was found. Thus, key genes involved in the development of intolerant inflammatory response have been identified. In addition, other key genes were identified that were initially associated with an intolerant inflammatory response and thus determine disorders of the inflammatory reaction leading to chronification of inflammation.
conclusionWe identified disturbances in gene associated with the development of intolerant immune response that may be relevant to atherosclerosis. Key genes responsible for the chronification of inflammation were discovered.
