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

Tongue pressure is a swallowing-related measure that correlates with handgrip strength, an indicator used in the assessment of sarcopenia. However, reduced tongue pressure in Parkinson's disease (PD) may reflect not only generalized muscle weakness but also PD-related motor control impairment, raising the possibility that tongue pressure and handgrip strength may show different patterns of association with PD motor symptoms. This study examined the patterns of association between tongue pressure and handgrip strength and motor symptoms assessed using Part III of the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) in patients with PD. A total of 49 individuals with PD aged 70-85 years were enrolled in this cross-sectional observational study. Tongue pressure, handgrip strength, and MDS-UPDRS Part III scores were assessed. Exploratory factor analysis of the MDS-UPDRS Part III items was conducted, followed by multiple regression analyses based on the total score and identified factors. After adjusting for age and sex, tongue pressure (
