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

Store-operated Ca(2+) entry (SOCE) has been found to be a rapidly activated robust mechanism in skeletal muscle fibres. It is conducted across the junctional membranes by stromal interacting molecule 1 (STIM1) and Orai1, which are housed in the sarcoplasmic reticulum (SR) and tubular (t-) system, respectively. These molecules that conduct SOCE appear evenly distributed throughout the SR and t-system of skeletal muscle, allowing for rapid and local control in response to depletions of Ca(2+) from SR. The significant depletion of SR Ca(2+) required to reach the activation threshold for SOCE could only be achieved during prolonged bouts of excitation-contraction coupling (EC coupling) in a healthy skeletal muscle fibre, meaning that this mechanism is not responsible for refilling the SR with Ca(2+) during periods of fibre quiescence. While Ca(2+) in SR remains below the activation threshold for SOCE, a low-amplitude persistent Ca(2+) influx is provided to the junctional cleft. This article reviews the properties of SOCE in skeletal muscle and the proposed molecular mechanism, assesses its potential physiological roles during EC coupling, namely refilling the SR with Ca(2+) and simple balancing of Ca(2+) within the cell, and also proposes the possibility of SOCE as a potential regulator of t-system and SR membrane protein function.
