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
backgroundRobot-assisted gait training (RAGT) has proven effective in addressing gait disorders in patients with stroke. However, its efficacy in patients with acute stroke has not yet been demonstrated. This pilot study is designed to evaluate the following: (1) feasibility of conducting a randomized controlled trial on RAGT for enhancing gait postacute stroke and (2) to obtain preliminary estimates regarding the potential efficacy of RAGT for achieving gait independence during the acute phase.
methodsWe will conduct an assessor-blinded, single-center, randomized controlled pilot trial involving 32 patients with acute stroke who are unable to walk. Participants will be randomly assigned to either the RAGT or the conventional gait training (CGT) groups. Each participant will receive 180 min of daily rehabilitation, including 60 min dedicated to gait training. The RAGT group will receive 40 min of RAGT and 20 min of CGT, while the CGT group will engage in 60 min of CGT. Interventions will continue for up to 8 weeks, or until participants achieve gait independence, as indicated by a Functional Ambulation Category score of ≥ 3. Feasibility outcomes will include recruitment, enrollment, protocol adherence, and retention rates. The primary clinical outcome will be the incidence of achieving gait independence during the intervention period. Secondary clinical outcomes will include gait performance measures, assessments of physical function and activity, and intervention dose. Adverse events associated with RAGT and CGT will also be documented to evaluate the safety of both interventions. DISCUSSION: Implementing RAGT during the acute phase of stroke may facilitate earlier attainment of gait independence compared to CGT. We aim to provide valuable insights into the feasibility of the proposed study design and generate preliminary data on the potential effects of RAGT on gait independence in the acute phase of stroke, providing a framework for future larger-scale trials.
trial registrationThis clinical trial was registered with the Japan Clinical Trials Registry (jRCT) on 19 June 2023 (registration number: jRCTs042230040). The study protocol was initially registered as version 1.0 and has since undergone minor amendments-currently on version 4.0. This protocol was written based on the latest version (ver. 4.0) registered with jRCT.
