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

objectiveThis study aimed to analyze the risk factors of intracranial hemorrhage (ICH) after deep brain stimulation (DBS) for idiopathic Parkinson's disease (PD).

methodsPatients who received DBS from March 2014 to December 2016 were retrospectively analyzed. The hemorrhage index was derived by combining the hemorrhagic volume and clinical manifestations of ICH. All patients with IHC were followed up for 2 years.

resultsComputed tomography showed 13 events of ICH in 11 patients (nine cases in the subthalamic nucleus), including eight cases with symptomatic hemorrhage (seven cases in the subthalamic nucleus). Hemorrhage was characterized by intracranial hematoma in the electrode puncture tract. Male sex and hypertension were significant risk factors for ICH. Hemorrhage in the preferred puncture side was significantly higher than that in the non-preferred puncture side. The mean hemorrhage index was 2.23 ± 0.83 in 11 patients, and no permanent neurological impairment was found during the 2-year follow-up. The effect of DBS on motor symptoms was similar in patients with and without ICH.

conclusionMale sex and hypertension are risk factors of ICH after DBS in PD. The risk of hemorrhage on the first puncture site is significantly higher than that on the second puncture site.
