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
Objective: To identify patterns of hip flexion assist orthosis (HFAO) use among ambulatory patients with multiple sclerosis (MS) and to assess factors influencing device adoption and discontinuation. Design: Retrospective chart review. Setting: Outpatient community physiatry clinic in New Westminster, British Columbia. Participants: Fifty-four ambulatory patients with MS who were previously assessed for HFAO use between November 2017 and October 2023. Patients were 35-92 years old, able to participate in gait evaluation, and had documented physical examinations. Patients with nonambulatory status or missing motor strength data were excluded. Participants were categorized into groups based on HFAO outcomes: regular use, no follow-up postpurchase, discontinued use, declined HFAO, or unsuccessful HFAO assessment. Interventions: Not applicable. Main Outcome Measures: Rates of HFAO use and discontinuation, hip flexor and knee extensor Medical Research Council (MRC) strength scores, lower-limb spasticity using the Modified Ashworth Scale (MAS), and qualitative factors associated with device adoption and nonuse. Results: Of 54 patients assessed, 48 were recommended an HFAO. Forty obtained a device, and 19 used it regularly. Thirteen patients discontinued use after a mean of 20 months, primarily due to pain/discomfort (38%) and device bulkiness (31%). Discontinuation was associated with higher lower-limb spasticity (mean MAS 1.5 vs 0.77, Conclusions: This study identifies clinical factors associated with HFAO use and discontinuation in ambulatory patients with MS, including hip flexion MRC scores of 1-3, knee extension MRC scores ≥3, and spasticity MAS scores <2. Comprehensive pre-prescription assessment, including pain screening and gait evaluation with and without a device, is recommended to optimize patient selection.
