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
Introduction: Ultra-high field (UHF) 7 tesla (7T) MRI offers unique diagnostic opportunities for clinical neuroimaging. However, broader clinical implementation remains limited because the reduced radiofrequency (RF) wavelength at 7T causes RF transmit field ( Methods: An open-face eight-channel transmit 64-channel receive (8Tx64Rx) 7T head coil was developed with electrical and mechanical ergonomic features designed to improve usability and imaging homogeneity. The coil was evaluated in an in vivo validation study assessing ease of use, participant comfort, diagnostic value, and image quality using questionnaires and structured scoring sheets. Imaging performance of the 8Tx64Rx coil was compared with that of a commercially available regulatory approved 7T head coil featuring single transmit (sTx) and a 32-channel receive array. Diagnostic image quality acquired using circularly polarized (CP) mode and pTx mode was additionally assessed and compared. Results: The 8Tx64Rx coil demonstrated image quality that was equivalent or superior to the commercial 7T head coil across evaluated measures. In particular, improved signal homogeneity was achieved within the posterior fossa and temporal lobes. The coil also supported practical clinical use through favorable ergonomic performance and user comfort during scanning. Diagnostic image quality was enhanced when using pTx approaches compared with conventional transmit configurations. Discussion: The developed 8Tx64Rx 7T head coil demonstrates the potential to advance clinical neuroimaging at UHF by improving
