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: Parakinesia brachialis oscitans (PBO), involuntary elevation of the paralyzed upper limb during yawning is a rare phenomenon after ischemic stroke, but its prognostic significance remains unclear due to limited systematic studies. Objective: To compare 3-month motor recovery between ischemic stroke patients with PBO, without PBO, and with spontaneously resolved PBO using a propensity score-matched design. Methods: This retrospective cohort study included 33 patients with PBO identified in the database as the PBO group, while the non-PBO group was selected from patients with acute ischemic stroke between March and June 2024. Two independent neurologists reviewed medical records according to standardized criteria to identify PBO (within 7 days of stroke onset) and collected baseline data from all patients within 24 h of stroke onset. PSM (1:2) was used to balance baseline characteristics (age, sex, vascular risk factors, stroke location, ASPECTS score, baseline Lovett score, and FMA score) between the PBO and non-PBO groups. The primary outcome was the FMA score at 3 months; the secondary outcome was the Lovett classification. All outcome assessors were blinded. Results: After matching, 26 PBO patients were matched to 52 non-PBO patients with balanced baseline characteristics. At 3 months, the PBO group showed significantly higher FMA scores (mean difference 3.77, 95% CI: -0.54-6.97; Conclusion: In this propensity-score-matched cohort study, the presence of PBO was associated with better recovery of motor function at 3 months. Early spontaneous resolution of PBO was associated with better fine motor outcomes compared to persistent PBO. These findings, which support the hypothesis, suggest that PBO may serve as a potential prognostic indicator warranting further prospective research.
