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
This paper presents ThongPaDisp, a low-cost, open-source, 3D-printed shuttlecock dispenser developed to automate shuttlecock feeding. The Grip-Gate-Push mechanism implemented in ThongPaDisp overcomes the limitations of conventional Grip-Gate (gravity-only) dispensing systems, which are prone to jamming caused by feather deformation and interlocking within the shuttlecock stack. The device is a modular feeder designed for integration with a shuttlecock launcher or standalone operation. The extraction sequence is actuated by three independent servo motors synchronized via a microcontroller. Two operating modes are supported: (1) automatic dispensing triggered by hand detection beneath the device, and (2) manual control via a wireless infrared remote for testing. The experimental evaluation utilized both new and used shuttlecocks across five repeated-dispensing trials. Under the Grip-Gate (gravity-only) configuration, jamming occurred in 3.3% (95% CI: [0.0%, 11.9%]) of trials for new shuttlecocks and 40.0% (95% CI: [11.9%, 68.2%]) of used shuttlecocks, with a mean fall time of 0.29 s. Conversely, the full Grip-Gate-Push configuration significantly improved reliability, exhibiting 0% and 1.7% (95% CI: [0.0%, 5.4%]) jamming for new and used shuttlecocks, respectively, with a mean release time of 0.61 s. The lightweight ThongPaDisp design (0.45 kg) is released as open-source hardware to enable easy fabrication, modification, and further development.
