Nitric oxide and its congeners in mitochondria: implications for apoptosis.
Review in Environmental health perspectives, 1998. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Apoptosis is an evolutionarily conserved form of physiologic cell death important for tissue development and homeostasis. The causes and execution mechanisms of apoptosis are not completely understood. Nitric oxide (NO) and its congeners, oxidative stress, Ca2+, proteases, nucleases, and mitochondria are considered mediators of apoptosis. Recent findings strongly suggest that mitochondria contain a factor or factors that upon release from the destabilized organelles, induce apoptosis. We have found that oxidative stress-induced release of Ca2+ from mitochondria followed by Ca2+ reuptake (Ca2+ cycling) causes destabilization of mitochondria and apoptosis. The protein product of the protooncogene bcl-2 protects mitochondria and thereby prevents apoptosis. We have also found that NO and its congeners can induce Ca2+ release from mitochondria. Thus, nitrogen monoxide (.NO) binds to cytochrome oxidase, blocks respiration, and thereby causes mitochondrial deenergization and Ca2+ release. Peroxynitrite (ONOO-), on the other hand, causes Ca2+ release from mitochondria by stimulating a specific Ca2+ release pathway. This pathway requires oxidized nicotinamide adenine dinucleotide (NAD+) hydrolysis to adenosine diphosphate ribose and nicotinamide. NAD+ hydrolysis is only possible when some vicinal thiols are cross-linked. ONOO- is able to oxidize them. Our findings suggest that NO and its congeners can induce apoptosis by destabilizing mitochondria via deenergization and/or by inducing a specific Ca2+ release followed by Ca2+ cycling.
