Gait Analysis in Rett Syndrome: Integrating Linear and Nonlinear Techniques.
Article in Journal of child neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Rett syndrome is a rare neurodevelopmental disorder that significantly impairs bipedal postural control and walking ability. This study quantifies the gait characteristics of 22 females with Rett syndrome (divided into 3 age groups) and compares them with age-matched neurotypical females. Bilateral sagittal plane joint angles of the hip, knee, and ankle were analyzed. Measures included joint range of motion, stride time, peak angular velocity, angle-angle diagrams, phase portrait areas, and asymmetries. Results revealed reduced joint range of motion and angular velocity in individuals with Rett syndrome, as well as greater asymmetries in gait parameters reflecting disruptions in bilateral coordination. Phase portraits and angle-angle diagrams indicated preserved coordination in proximal joints but greater variability at the ankle. Ankle movement in individuals with Rett syndrome aged 9-14 years showed a closer resemblance to Controls. These findings identify underlying lower limb motion patterns that contribute to gait deficits in Rett syndrome, guiding future targeted interventions to improve their mobility.
