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
The purpose of this study was to gain further insight into passive force enhancement by testing whether passive force enhancement occurs in single myofibrils. Myofibrils (n = 6) isolated from rabbit psoas muscle were fixed at a sarcomere length of 2.4 microm, and then stretched passively and actively to a sarcomere length of 3.4 microm. Passive force after deactivation of the myofibrils was increased after active compared to passive stretching. Therefore, passive force enhancement, previously observed in muscle and fiber preparations, also occurs in single myofibrils. Passive force enhancement in myofibrils ranged from 86 to 145% of the steady-state force observed after passive stretch. Because titin is the main source of passive force in myofibrils, we propose that titin might be responsible for passive force enhancement observed in myofibrils. We propose that this might occur through an increase in stiffness when calcium concentration increases upon activation.
