Responsiveness of the Revised Low Vision Independence Measure (LVIM-R).
Observational study in The American journal of occupational therapy : official publication of the American Occupational Therapy Association. 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
importanceThe Low Vision Independence Measure (LVIM) was designed to measure the effectiveness of occupational therapy to improve visual ability in low vision rehabilitation.
objectiveTo validate the Revised LVIM (LVIM-R) as an outcome measure by determining its sensitivity to visual ability changes after occupational therapy.
designIn this observational study, LVIM-R scores were collected before and after customary low vision intervention.
settingHome health agency or outpatient facility.
participantsForty-four participants with a mean age of 80.2 yr (standard deviation = 11.2) and an average length of visual impairment of 6.2 yr. Twenty-three participants (52.3%) were treated in an outpatient setting, and 21 (47.7%) were treated in the home. The majority of participants were non-Hispanic White (92.8%) and had macular degeneration (54.5%).
interventionCustomary low vision intervention by occupational therapists. OUTCOMES AND MEASURES: LVIM-R scores were collected before and after intervention, and participants' pre- and posttest scores were anchored into Rasch-calibrated item parameters.
resultsPaired t tests demonstrated significant increases in person measures with large effect sizes for both constructs of the LVIM-R, the visual field or scotoma (t[43] = 6.46, p < .0001; Cohen's d = 0.92) and visual acuity (t[43] = 9.08, p < .0001; Cohen's d = 1.14) constructs. CONCLUSIONS AND RELEVANCE: The LVIM-R is sensitive to changes in visual ability in clients who have good rehabilitation potential and can be used to examine the effectiveness of occupational therapy for low vision. WHAT THIS ARTICLE ADDS: The LVIM-R is useful for measuring occupational therapy outcomes in low vision rehabilitation in the home or in outpatient settings.
