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 binding of calcium to cardiac troponin C (cTnC) enhances the binding of troponin I (cTnI) switch region to the regulatory domain of cTnC (cNTnC) and triggers muscle contraction. Several molecules alter the response of the sarcomere by targeting this interface; virtually all have an aromatic core that binds to the hydrophobic pocket of cNTnC and an aliphatic tail that interacts with the switch region of cTnI. W7 has been extensively studied, and the positively charged tail has been shown to be important for its inhibitory action. Herein we investigate the importance of the aromatic core of W7 by synthesizing compounds that have the core region of calcium activator dfbp-o with various lengths of the same tail (D-series). These compounds all bind more tightly to cNTnC-cTnI chimera (cChimera) than the analogous W-series compounds and show increased calcium sensitivity of force generation and ATPase activity, demonstrating that the cardiovascular system is tightly balanced.
