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
backgroundGait disturbances are among the most disabling manifestations of cerebral palsy (CP) and substantially affect functional mobility and quality of life. Robot-assisted gait training (RAGT) has been introduced to improve gait performance; however, its effects on lower-limb kinematics remain inconsistent. The aim of this study was to evaluate changes in sagittal-plane gait kinematics in children with CP following a four-week gait rehabilitation program using the PRODROBOT robotic gait trainer.
methodsA prospective quasi-experimental pre-post study with a reference group was conducted. Ten children with spastic cerebral palsy at GMFCS level III aged 8-13 years completed a four-week intervention comprising 20 sessions of robot-assisted gait training. Three-dimensional gait analysis (Vicon) was performed before (KF1) and within 72 h after the end of the intervention (KF2); for each participant, 15 gait cycles were averaged. Eighteen typically developing children aged 7-14 years constituted the normative reference group (CG) and were assessed once. Sagittal plane angular waveforms for the hip, knee, and ankle joints were compared using the difference factor (
resultsThe intervention produced selective changes in lower-limb kinematics. At the ankle joint, the range of motion deficit in the sagittal plane relative to the CG decreased from 4.5° to 2.9°, and the difference modulus at 55-60% of the gait cycle decreased from 7.5% to 4.0%. At the knee joint, the difference factor relative to the CG decreased from
conclusionsRobot-assisted gait training with the PRODROBOT system produced selective improvements in sagittal-plane gait kinematics in children with cerebral palsy, with the most pronounced effects observed at the ankle joint and, to a lesser extent, the knee. The intervention did not restore a normal gait pattern, particularly at the hip joint. These findings suggest that robotic gait training may serve as a valuable component of comprehensive rehabilitation but should be combined with interventions targeting muscle strength, joint mobility and postural control. Larger randomized studies with long-term follow-up are needed to confirm the clinical effectiveness of this approach.
