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

Small-angle X-ray scattering (SAXS) and Fourier transform infrared (FTIR) spectroscopy were used to investigate structural peculiarities of two types of amyloid aggregates of smooth muscle titin, which differed in their morphology and ability to disaggregate, and differently bound thioflavin T dye. SAXS showed that the structure/shape of the two titin aggregate types was close to a flat shape. FTIR spectroscopy revealed no differences in the secondary structure of the two types. These data suggest that both types of "flat-shape" titin aggregates are identical in their secondary structure and, as shown previously, have a quaternary cross-β structure. An assumption was made that the most stable supramolecular complexes of a cross-β structure, which do not differ in their secondary structure, formed first during the aggregation of smooth muscle titin. Then, depending on ambient conditions, these supramolecular structures could form titin aggregates of different morphology and properties.
