The Boston Assessment of Traumatic Brain Injury Lifetime, Second Edition (BATL-2): Development and Initial Psychometric Evaluation in Post-9/11 Military Veterans.
Article in The Journal of head trauma rehabilitation. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
objectiveDescribe the development and initial psychometric evaluation of the Boston Assessment of Traumatic Brain Injury (TBI) Lifetime, Second Edition (BATL-2).
settingThe Translational Research Center for TBI and Stress Disorders (TRACTS) located at two large VA medical centers.
participantsRandom selection of 100 US post-9/11 military Veterans enrolled at TRACTS Boston primary site and 20 Veterans enrolled at TRACTS Houston secondary site.
designSecondary analysis of a prospective longitudinal cohort study. MAIN MEASURES: Boston Assessment of TBI-Lifetime (BAT-L), BATL-2, Ohio State University Traumatic Brain Injury Identification Method (OSU-TBI-ID).
resultsBATL-2 instrument development included National Institute of Neurological Disorders and Stroke (NINDS) and American Congress of Rehabilitation Medicine (ACRM) field updates to TBI diagnostics, iterative review and feedback from stakeholders, and data-driven revisions. The BATL-2 demonstrated excellent diagnostic agreement with TBI diagnosis from the OSU-TBI-ID (κ = 0.94; sensitivity 100%; specificity 87.0%-92.5%). Internal consistency and diagnostic agreement between BATL-2 and the first edition BAT-L were high (Cronbach's α = 0.83; κ = 0.94). BATL-2 demonstrated convergent validity with neurobehavioral symptoms ( r = .260, p = .012) and discriminant validity with measures of depression ( r = .004, p = .966) and tobacco use ( r = .086 to .307, p > .553). Replication in a secondary sample showed robust diagnostic agreement (κ = 0.97).
conclusionsResults indicate that the BATL-2 is a valid and reliable measure of retrospective TBI diagnosis. Importantly, BATL-2 provides continuity of evidence-based assessment of TBI, including forward compatibility with updated field TBI diagnostic criteria while maintaining backward compatibility with BAT-L and previous TBI guidelines. The BATL-2 improves retrospective brain injury characterization by reducing administration time burden, assessing repetitive head impacts (RHI) and military occupational blast exposures (MOBE), and incorporating updated field standards.
