Passive stiffness of Drosophila IFM myofibrils: a novel, high accuracy measurement method.
Article in Journal of muscle research and cell motility, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
As the smallest muscle-cell substructure that retains the intact contractile apparatus, the single myofibril is considered the optimal specimen for muscle mechanics, although its small size also poses some technical difficulties. Myofibrils from Drosophila indirect flight muscle (IFM) are particularly difficult to study because their high passive stiffness makes them hard to handle, and too resistant to stretch to produce enough elongation for the accurate measurement of sarcomere length change. In this study, we devised a novel method for accurate stiffness measurement of single relaxed myofibrils using microfabricated cantilevers and phase contrast microscopy. A special experimental protocol was developed to minimize errors, and some data analysis strategies were used to identify and exclude spurious data. Remarkably consistent results were obtained from Drosophila IFM myofibrils. This novel, high accuracy method is potentially an effective tool for detecting small passive stiffness change in muscle mutants.
