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

backgroundDopamine agonist therapy is the main risk factor for impulse control disorders in Parkinson's disease (PD). However, it is unclear whether bilateral deep brain stimulation of the subthalamic nucleus also causes impairment in decision making.

objectivesTo assess the role of dopamine agonist therapy and deep brain stimulation on reflection impulsivity in non-demented patients with PD.

methodsWe recruited 61 PD patients, 20 treated with L-dopa in combination with a dopamine agonist, 14 taking L-dopa monotherapy, a further 16 PD patients with bilateral subthalamic nucleus deep brain stimulation treated with L-dopa in combination with a dopamine agonist, and 11 PD patients with bilateral subthalamic nucleus deep brain stimulation taking L-dopa but not a dopamine agonist. Results were compared with 18 healthy controls. Patients who had evidence of impulsive compulsive behaviour were excluded. Reflection impulsivity was assessed with the beads task, which is a validated information sampling task.

resultsAll patients treated with a dopamine agonist gathered significantly less information and made more irrational decisions than all other groups regardless of whether they had surgical treatment.

conclusionsOur results imply that dopamine agonist therapy but not deep brain stimulation leads to "reflection impulsivity" in PD.
