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 skeletal isoform of Ca2+ release channel, RyR1, plays a central role in activation of skeletal muscle contraction. Another isoform, RyR3, has been observed recently in some mammalian skeletal muscles, but whether it participates in regulating skeletal muscle contraction is not known. The expression of RyR3 in skeletal muscles was studied in mice from late fetal stages to adult life. RyR3 was found to be expressed widely in murine skeletal muscles during the post-natal phase of muscle development, but was not detectable in muscles of adult mice, with the exception of the diaphragm and soleus muscles. RyR3 knockout mice were generated, and it was shown that skeletal muscle contraction in these mice was impaired during the first weeks after birth. In skeletal muscles isolated from newborn RyR3(-/- )mice, but not in those from adult mice, the twitch elicited by electrical stimulation and the contracture induced by caffeine were strongly depressed. These results provide the first evidence that RyR3 has a physiological role in excitation-contraction coupling of neonatal skeletal muscles. The disproportion between the low amount of RyR3 and the large impact of the RyR3 knockout suggests that this isoform contributes to the amplification of Ca2+ released by the existing population of ryanodine receptors (RyR1).
