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

While deep brain stimulation of the subthalamic nucleus (STN-DBS) has evolved to an evidence-based standard treatment for Parkinson's disease (PD), the targeted cerebral networks are poorly described and no objective predictors for the postoperative clinical response exist. To elucidate the systemic mechanisms of DBS, we analysed cerebral grey matter properties using cortical thickness measurements and addressed the dependence of structural integrity on clinical outcome. Thirty one patients with idiopathic PD without dementia (23 males, age: 63.4 ± 9.3, Hoehn and Yahr: 3.5 ± 0.8) were selected for DBS treatment. The patients underwent whole-brain preoperative T1 MR-Imaging at 3 T. Grey matter integrity was assessed by cortical thickness measurements with FreeSurfer. The clinical motor outcome markedly improved after STN-DBS in comparison to the preoperative condition. The cortical thickness of the frontal lobe (paracentral area and superior frontal region) predicted the clinical improvement after STN-DBS. Moreover, in patients with cortical atrophy of these areas a higher stimulation voltage was needed for an optimal clinical response. Our data suggest that the effects of STN-DBS in PD directly depend on frontal lobe grey matter integrity. Cortical atrophy of this region might represent a distinct predictor of a poor motor outcome after STN-DBS in PD patients.
