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 primary purpose of this study was to assess the feasibility of applying a novel approach to measure myosin heavy chain (MHC) isoform expression, glucose uptake, fiber volume, and protein abundance in single muscle fibers of adult (9 months) and old (25 months) rats. Epitrochlearis muscle fibers were successfully isolated and analyzed for MHC isoform expression, glucose uptake, fiber volume, and protein (COXIV, APPL1, IκB-β) abundance. Insulin-stimulated glucose uptake by single fibers did not differ between age groups, but there was a significant difference between fiber types (IIA > IIX > IIB/X ≈ IIB). There were also significant main effects of fiber type on APPL1 (IIX > IIB) and COXIV (IIA > IIX > IIB/X ≈ IIB) abundance, and IIB fibers were significantly larger than IIA fibers. This study established the feasibility of a new approach for assessing age-related differences in muscle at the single-fiber level and demonstrated the magnitude and rank order for fiber-type differences in insulin-stimulated glucose uptake of 9-month-old and 25-month-old rats.
