1 · What the graph read from it

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.

2 · The registry

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

backgroundMagnetic resonance-guided focused ultrasound (MRgFUS) targeting the thalamic ventral intermediate nucleus (VIM) is an innovative treatment for drug-refractory essential tremor (ET). The relationship between lesion characteristics, dentate-rubro-thalamic-tract (DRTT) involvement and clinical benefit remains unclear.

objectivesTo investigate whether clinical outcome is related to lesion volume and/or its overlap with the DRTT. To compare the reliability of probabilistic versus deterministic tractography in reconstructing the DRTT and improving VIM targeting.

methodsForty ET patients who underwent MRgFUS thalamotomy between 2019 and 2022 were retrospectively analyzed. Clinical outcomes and adverse effects were recorded at 1/6/12 months after the procedure. The DRTT was generated using deterministic and probabilistic tractography on preoperative diffusion-tensor 3 T-images and location and volume of the lesion were calculated.

resultsProbabilistic tractography identified both decussating (d-DRTT) and non-decussating (nd-DRTT) components of the DRTT, whereas the deterministic approach only identified one component overlapping with the nd-DRTT. Despite the lesions predominantly intersecting the medial portion of the d-DRTT, with a significantly greater overlap in responder patients, we observed only a non-significant correlation between tremor improvement and increased d-DRTT-lesion overlap (r = 0.22, P = 0.20). The lesion volume demonstrated a significant positive correlation with clinical improvement at 1-day MRI (r = 0.42, P < 0.01).

conclusionVariability in the reconstructed DRTT position relative to the lesion center of mass, even among good responders, suggests that this fiber bundle is unlikely to be considered the sole target for a successful MRgFUS thalamotomy in ET. Indirect individualized targeting allows for more precise and reproducible identification of actual treatment coordinates than the direct method.
