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

Background: Essential tremor (ET) is primarily characterized by action tremor, but is also associated with various non-motor symptoms (NMS). However, the diagnostic relevance of NMS in ET remains unclear. This study aimed to compare NMS and motor symptoms of ET with those of Parkinson's disease-tremor dominant type (PD-TDT) and healthy controls (HCs) and to identify the presence and diagnostic relevance of NMS. Methods: Twenty-three ET patients, 23 PD-TDT patients, and 22 HCs were enrolled. Diagnoses of ET and PD were confirmed using Movement Disorder Society (MDS) criteria and Dopamine transporter single-photon emission computed tomography. Motor symptoms, NMS and quality of life (QOL) were evaluated using validated scales, including the Clinical Rating Scale for Tremor (CRST), MDS-Unified Parkinson's Disease Rating Scale (UPDRS), Non-Motor Symptoms Scale for Parkinson's Disease (NMSS), Odor Stick Identification Test for Japanese (OSIT-J), and Quality of Life in Essential Tremor Questionnaire (QUEST). Results: ET patients had significantly higher NMSS total scores and MDS-UPDRS part IB scores than HCs, with more severe sleep disturbances, fatigue, and urinary problems. CRST scores were significantly correlated with QUEST scores. Logistic regression identified CRST Part B and OSIT-J as key factors distinguishing ET from PD-TDT, with 87% sensitivity and 90% specificity. Discussion: ET patients showed more severe NMS than HCs. Differentiating ET from PD-TDT requires motor and sensory assessments, highlighting the diagnostic relevance of NMS. Comprehensive evaluation is essential for accurate diagnosis and management of ET.
