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

Myofibrillogenesis was studied in cultured chick cardiomyocytes using indirect immunofluorescence microscopy and antibodies against alpha- and gamma-actin, muscle and nonmuscle tropomyosin, muscle myosin, and titin. Initially, cardiomyocytes, devoid of myofibrils, developed variable numbers of stress fiber-like structures with uniform staining for anti-muscle and nonmuscle actin and tropomyosin, and diffuse, weak staining with anti-titin. Anti-myosin labeled bundles of filaments that exhibited variable degrees of association with the stress fiber-like structures. Myofibrillogenesis occurred with a progressive, and generally simultaneous, longitudinal reorganization of stress fiber-like structures to form primitive sarcomeric units. Titin appeared to attain its mature pattern before the other major contractile proteins. Changes in the staining patterns of actin, tropomyosin, and myosin as myofibrils matured were interpreted as due to longitudinal filament alignment occurring before ordering in the axial direction. Non-muscle actin and tropomyosin were found with sarcomeric periodicity in the initial stages of sarcomere myofibrillogenesis, although their staining patterns were not identical. The localization of the "sarcomeric" proteins alpha-actin and muscle tropomyosin in stress fiber-like structures and the incorporation of non-muscle proteins in the initial stages of sarcomere organization bring into question the meaning of "sarcomeric" proteins in regard to myofibrillogenesis.
