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
Thoracic outlet syndrome (TOS) results from compression of neurovascular structures. Dynamic MRI may enhance diagnostic accuracy; however, conventional rigid coils are suboptimal for imaging during functional maneuvers. This study compared a custom-built flexible modular coil (ModFlex) with a conventional torso coil, focusing on the interscalene (ISS) and costoclavicular spaces (CCS). Nine healthy volunteers participated in 3 T TOS MRI using both coils. The signal-to-noise ratio (SNR) was calculated in two regions of interest (ISS and CCS). Additionally, g-factors were evaluated for simulated GRAPPA parallel imaging factors from 3 to 6. Two clinicians visually rated T1-weighted sagittal images to assess ModFlex coil performance. Quantitative data were compared using the Wilcoxon signed-rank and the ranks with the sign test. The ModFlex demonstrated a significantly higher SNR in the CCS (+ 39%, p = 0.004), a trend toward higher SNR in the ISS (+ 17%, p = 0.098), and significantly lower g-factors (i.e., higher parallel imaging performance) across all acceleration levels (p < 0.008). The clinicians' evaluation was generally consistent with quantitative findings, although not conclusive. GRAPPA acceleration provided better image quality than SMS (p = 0.008). Overall, modular flexible coils support faster, higher-quality dynamic TOS MRI protocols, potentially improving diagnostic reliability, and patient comfort.
