Evaluation of Partial Volume Correction Techniques for Sodium MRI of the Achilles Tendon.
Article in Magnetic resonance in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo evaluate partial volume correction (PVC) techniques for sodium MRI of the Achilles tendon in situ and in vivo.
methodsFive PVC methods were evaluated including a volume ratio of the proton and sodium segmentations (PSSR), a modified least trimmed square (3D-mLTS) linear regression, a geometric transfer matrix (GTM) approach, a single target correction (STC), and a novel estimated single target correction (eSTC). Their performance was tested using simulated data and 3 T MR data of two volunteers' Achilles tendons acquired at different resolutions: 1.5, 2.0, 3.0, and 4.5 mm
resultsIn the simulation, all PVC methods reduced the difference between the actual and calculated concentrations and were 11.69 ± 6.17 mM without PVC, 4.90 ± 5.40 mM with the PSSR, 4.86 ± 5.19 mM with the mLTS, 1.72 ± 4.13 mM with the GTM, 0.36 ± 1.77 mM with STC and 0.26 ± 1.63 mM with the eSTC. In vivo, the difference in aTSCs between the lower and the highest resolution decreased with all PVCs ranging from 3.6 to 38.8 mM without PVC, 2.8-20.4 mM with PSSR, 4.5-25.9 mM with mLTS, 0.9-7.8 mM with GTM, 0.1-23.8 mM with STC, and 0.7-7.7 mM with eSTC.
conclusionPVC generally improved the accuracy of aTSC calculations. The newly introduced eSTC produced the most accurate results for the Achilles tendon.
