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

backgroundFemale sex is an independent fall risk factor in Parkinson's disease (PD), yet sex-specific fall patterns remain unclear.

objectivesTo compare sex-specific fall risk and outcomes across PD, prodromal alpha-synucleinopathy (PAS), and healthy controls (HC); estimate fall frequency across PD progression; and assess how sex modifies fall risk and outcomes.

methodsFall outcomes were analyzed in the Parkinson's Progression Markers Initiative. Yearly rates of rare and frequent falls were estimated by time since diagnosis. PD participants were classified as never, rare, or frequent fallers. Clinical measures included motor, cognitive, behavioral, sleep, and autonomic domains. Outcomes included injuries and healthcare utilization. Regression models adjusted for age, sex, and disease duration with Benjamini-Hochberg correction.

resultsAmong 3100 participants (937 PD, 1926 PAS, 237 HC; 6977 visits), PD participants had higher odds of falling than PAS (OR 1.66, 95% CI 1.46-1.87) and HC (OR 4.03, 95% CI 3.14-5.23). In PD and PAS, females had higher odds of injuries (OR 1.50, 95% CI 1.20-1.88) and fractures (OR 1.62, 95% CI 1.15-2.29), including hip (OR 2.30, 95% CI 1.09-4.91) and upper-extremity fractures (OR 2.67, 95% CI 1.51-4.85). Within PD, falls increased with disease duration and were higher in females (7 years: 42% vs. 32%; 14 years: 88% vs. 61%) despite milder clinical profiles. Across the Neuronal Synuclein Disease-Integrated Staging System (NSD-ISS) stages, fall occurrence was higher in females.

conclusionFalls increase with disease duration and NSD-ISS stage. Female PD participants are at greater risk despite milder symptoms, supporting sex-specific prevention strategies.
