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 troponin complex plays a central role in regulating the contraction and relaxation of striated muscles. Among the three protein subunits of troponin, the calcium receptor subunit, TnC, belongs to the calmodulin family of calcium signaling proteins whereas the inhibitory subunit, TnI, and tropomyosin-binding/thin filament-anchoring subunit, TnT, are striated muscle-specific regulatory proteins. TnI and TnT emerged early in bilateral symmetric invertebrate animals and have co-evolved during the 500-700 million years of muscle evolution. To understand the divergence as well as conservation of the structures of TnI and TnT in invertebrate and vertebrate organisms adds novel insights into the structure-function relationship of troponin and the muscle type isoforms of TnI and TnT. Based on the significant growth of genomic database of multiple species in the past decade, this focused review studied the primary structure features of invertebrate troponin subunits in comparisons with the vertebrate counterparts. The evolutionary data demonstrate valuable information for a better understanding of the thin filament regulation of striated muscle contractility in health and diseases.
