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

A comprehensive, patient-centered conceptual model of early Parkinson's is lacking and is greatly needed. A systematic review and meta-synthesis of qualitative and quantitative research was conducted by a multi-stakeholder taskforce using JBI Mixed Methods Review criteria and GRADE-CERQual standards for assessment of evidence. Over 340 symptoms and impacts were identified across ten symptom domains (Movement, Cognitive, Psychiatric, Sleep, Sensory, Speech, Digestive, Urinary, Sexual, Autonomic) and two impact domains (Physical and Psychosocial functioning). A wide range of motor and non-motor symptoms were present in early disease, with strongest support for tremor, dexterity, gait, stiffness, slow movements, cognitive, mood, and sleep alterations, urinary dysfunction, constipation, pain, and fatigue. These affected mobility, self-concept, coping, effort of living, interactions and important activities, with evidence of many understudied concepts. This model offers the most comprehensive catalogue of symptoms and impacts in Parkinson's to date and will support clinical practice and endpoint selection for therapeutic trials.
