Autosomal dominant inheritance of brain cardiolipin fatty acid abnormality in VM/DK mice: association with hypoxic-induced cognitive insensitivity.
Article in Lipids, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Cardiolipin is a complex polyglycerol phospholipid found almost exclusively in the inner mitochondrial membrane and regulates numerous enzyme activities especially those related to oxidative phosphorylation and coupled respiration. Abnormalities in cardiolipin can impair mitochondrial function and bioenergetics. We recently demonstrated that the ratio of shorter chain saturated and monounsaturated fatty acids (C16:0; C18:0; C18:1) to longer chain polyunsaturated fatty acids (C18:2; C20:4; C22:6) was significantly greater in the brains of adult VM/DK (VM) inbred mice than in the brains of C57BL/6 J (B6) mice. The cardiolipin fatty acid abnormalities in VM mice are also associated with alterations in the activity of mitochondrial respiratory complexes. In this study we found that the abnormal brain fatty acid ratio in the VM strain was inherited as an autosomal dominant trait in reciprocal B6 × VM F1 hybrids. To evaluate the potential influence of brain cardiolipin fatty acid composition on cognitive sensitivity, we placed the parental B6 and VM mice and their reciprocal male and female B6VMF1 hybrid mice (3-month-old) in a hypoxic chamber (5 % O2). Cognitive awareness (conscientiousness) under hypoxia was significantly lower in the VM parental mice and F1 hybrid mice (11.4 ± 0.4 and 11.0 ± 0.4 min, respectively) than in the parental B6 mice (15.3 ± 1.4 min), indicating an autosomal dominant inheritance like that of the brain cardiolipin abnormalities. These findings suggest that impaired cognitive awareness under hypoxia is associated with abnormalities in neural lipid composition.
