Variation in the lipoprotein lipase gene influences exercise-induced left ventricular growth.
Trial report in Journal of molecular medicine (Berlin, Germany), 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The adult heart relies predominantly on fatty acids (FA) for energy generation, and defects in FA catabolism cause dramatic left ventricular (LV) growth in early age. Since lipoprotein lipase (LPL) is the key enzyme in plasma triglyceride catabolism and is highly expressed in the myocardium, we investigated an association between the functional LPL gene serine 447 stop (S447X) variant and exercise-induced LV growth. The S447X variant was genotyped in 146 British Army recruits undergoing a 10-week exercise programme. Over the training period, X447 allele carriers showed less LV growth than S447 homozygotes (SS, 5.8+/-0.7%; SX, 2.2+/-1.5%; P=0.03) and a decrease in systolic blood pressure (DeltaSBP: SS, 1.9+/-1.3 mmHg; SX, -5.7+/-2.2 mmHg; P=0.015). Although LPL genotype did not significantly predict LV growth with DeltaSBP in statistical modelling (LPL, P=0.14; DeltaSBP, P=0.06), regression analysis indicated that LPL S447X genotype effect on DeltaSBP accounted for only 20% of the effect on LV growth. In multivariate analysis, LPL, peroxisome-proliferator-activated receptor alpha and angiotensin-converting enzyme genotypes were independent predictors of cardiac growth. Thus, LPL S447X genotype influenced exercise-induced changes in LV mass and SBP. Change in blood pressure accounted for a proportion of LV growth. These data suggest that increased myocardial FA availability may reduce exercise-induced LV growth.
