1 · What the graph read from it

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.

2 · The registry

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 molecular basis of human heart failure is unknown. Alterations in calcium homeostasis have been observed in failing human heart muscles. Intracellular calcium-release channels regulate the calcium flux required for muscle contraction. Two forms of intracellular calcium-release channels are expressed in the heart: the ryanodine receptor (RyR) and the inositol 1,4,5-trisphosphate receptor (IP3R). In the present study we showed that these two cardiac intracellular calcium release channels were regulated in opposite directions in failing human hearts. In the left ventricle, RyR mRNA levels were decreased by 31% (P < 0.025) whereas IP3R mRNA levels were increased by 123% (P < 0.005). In situ hybridization localized both RyR and IP3R mRNAs to human cardiac myocytes. The relative amounts of IP3 binding sites increased approximately 40% compared with ryanodine binding sites in the failing heart. RyR down-regulation could contribute to impaired contractility; IP3R up regulation may be a compensatory response providing an alternative pathway for mobilizing intracellular calcium release, possibly contributing to the increased diastolic tone associated with heart failure and the hypertrophic response of failing myocardium.
