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

backgroundNew sophisticated deep brain stimulation (DBS) systems enabling steering of current and aiming at improving further motor outcome and decreasing side effects have virtually replaced old omnidirectional systems, despite being more labor-intensive and expensive.

objectivesThe objective was to evaluate whether modern directional DBS resulted in better motor improvement compared to "old" omnidirectional DBS.

methodsPublications on subthalamic nucleus (STN)-DBS from the "old" period were compared to modern publications, focusing on severity of motor symptoms at baseline and motor outcome at various intervals after surgery.

resultsAlthough patients from old DBS era had a more advanced disease at baseline than those treated with modern DBS hardware, they benefitted more from STN-DBS and showed a higher percentage decrease in dopaminergic medication.

conclusionsThe new directional DBS does not result in better motor outcome compared to the older omnidirectional DBS. However, it may, in some cases, contribute to decreasing some side effects of stimulation such as dysarthria.
