Reinforcement-Based Head Scan Training for Drivers With Homonymous Visual Field Loss: Improves Blind-Side Detection.
Trial report in Archives of physical medicine and rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo evaluate whether a reinforcement-based head scanning training program improves blind-side hazard detection in drivers with homonymous visual field loss.
designSingle-arm nonrandomized clinical trial with 1-month follow-up.
settingResearch laboratory.
participantsInclusion criteria included ≥3 months post-onset hemianopia or quadrantanopia, no neglect or major cognitive decline, and current or former driving experience. Sixteen of 23 volunteers met criteria and completed the study (median age=52.5y; 56% left-sided field loss).
interventionsParticipants completed three 1-hour sessions of a reinforcement-based head scanning training program in a driving simulator. An auditory reminder cue served as immediate, error-contingent feedback, sounding from a loudspeaker on the participant's blind-side if they failed to make a large, early head scan to their blind-side before an intersection. MAIN OUTCOMES MEASURES: The primary outcomes were rates of proactive blind-side scanning (the proportion of intersections with an early large head scan) and blind-side hazard detection (the proportion of hazards detected) assessed without reminder cues at pretraining, 1 week posttraining, and 1 month posttraining. All hypotheses were prespecified.
resultsProactive blind-side head scanning increased significantly from 17.5% (95% CI, 8.9%-26.0%) at pretraining to 83.6% (95% CI, 76.5%-90.7%) at 1 week posttraining and 72.6% (95% CI, 63.4%-81.9%) at 1 month posttraining. Likewise, blind-side hazard detection improved significantly from 55.6% (95% CI, 41.3%-69.9%) to 85.6% (95% CI, 76.3%-95.0%) at 1 week posttraining and 82.5% (95% CI, 70.1%-94.9%) at 1 month posttraining. Improvements were primarily because of fewer scanning-related errors.
conclusionsThree sessions of reinforcement-based head scanning training significantly improved blind-side head scanning and hazard detection in drivers with homonymous visual field loss, with benefits lasting at least 1 month. These results support the promise of this rehabilitation approach for poststroke driving and warrant further evaluation in a randomized controlled trial.
