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

objectiveThe outcomes of motor and nonmotor features of Parkinson's disease (PD) following deep brain stimulation (DBS) vary among its subtypes. We tested whether preoperative motor subtyping using the modified tremor/postural instability and gait difficulty ratio (T/P ratio) could indicate the short-term motor, nonmotor and quality of life (QOL) outcomes of subthalamic nucleus (STN) DBS.

methodsIn this prospective study, 39 consecutive STN DBS patients were assessed in the drug-OFF state before surgery and subtyped according to the T/P ratio. Patients were reassessed 6 months after surgery in the stimulation ON-drug-OFF state, and the percentage changes in motor, nonmotor and QOL scores (Parkinson's Disease Quality of Life Questionnaire [PDQ-39]) were calculated.

resultsThe modified T/P ratio was moderately and positively correlated with the percentage change in the Unified Parkinson's Disease Rating Scale III score in the OFF state, the sum of cardinal motor signs, the Non-Motor Symptom Scale score, and QOL (PDQ-39).

conclusionPreoperative PD motor subtyping can be used as an indicator of the short-term outcomes of STN DBS in PD patients.
