A Multi-view Open-access Dataset of Paired Knee MRI for Motion Artifact Removal.
Article in Scientific data, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Magnetic resonance imaging (MRI) has become a standard examination method for the knee, facilitating the identification of a range of knee-related issues, including injuries, arthritis, and other conditions. The lengthy image acquisition time inherent to MRI results in the generation of motion artifacts, which in turn impairs the efficiency of MRI applications. To address this challenge, we present a multi-view, multi-sequence knee joint paired MRI dataset (image with motion artifact vs. Ground Truth obtained after rescanning), named Knee MRI for Artifact Removal (KMAR)-50K, which includes 1,190 patients, 1,444 pairs of MRI sequences, and 62,506 scan images. The dataset comprises images of anonymous paired NIfTI files that have undergone bias field correction, maximum minimum normalization, and paired image spatial registration in sequence. The objective of our data-sharing program is to facilitate the benchmark testing of methods of knee MRI motion artifact removal. Benchmarking three models revealed U-Net's superior transverse plane performance (PSNR = 28.468, SSIM = 0.927) with fastest inference (0.5 s/volume), highlighting its clinical value in accuracy-efficiency balance.
