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
Purpose: A recent cadaveric study revealed that the tensed calcaneofibular ligament (CFL) lifts the peroneal tendons. This suggests that the CFL acts as a tensioner to transmit the contractile activity of the peroneal muscles effectively. However, the onset points of the lift-up and actual CFL-generated contact pressures against the peroneus brevis tendon (PBT) remain unclear. This cadaveric study aimed to elucidate the lift-up phenomenon through the quantitative measurement of changes in the contact pressure between the CFL and PBT under precise monitoring of the ankle position. Methods: We performed a quantitative analysis of 11 cadaveric ankle specimens with a pressure-sensitive sensor under accurate three-axial joint angle monitoring using inertial measurement units. The output values from the pressure-sensitive sensor inserted between the CFL and PBT were measured at different inversion (INV) angles, converted into contact pressure values (mV), and statistically analysed. Results: Although the onset points differed across the samples, the contact pressure values of all samples showed a positive change as the INV angle increased. Friedman and post hoc Steel-Dwass tests revealed significant differences between INV 0° versus 10° ( Conclusion: Our findings strongly suggest that INV enhances the tensioner effect of CFL. Specifically, an ankle with a relatively early onset point and high contact pressure may exhibit a superior tensioner effect and, through the control of peroneal tendons, potentially prevent an ankle sprain. Level of Evidence: Not applicable.
