1 · What the graph read from 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.

2 · The registry

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

backgroundFor selected patients at increased fall risk, physical therapy may include instruction to look around and observe the environment to identify obstacles, known as visual scanning or tracking, and avoid them. Whether visual scanning reduces fall risk more broadly in the general population is unknown.

methodsUsing data from the Mexico Health and Aging Study (MHAS), a longitudinal, nationally representative study of adults 50 years of age and older in Mexico (n = 13,850), we measured the association between visual scanning test performance and three fall-related outcomes: any fall in the previous 2 years, recurrent falls, and falls with injury. We conducted both cross-sectional and longitudinal analyses over 3 years of follow-up; logistic regression models were adjusted for demographic variables, self-reported comorbidities, daily activity limitations, and a standardized, composite measure of attention (Z-score of summed backwards counting and serial 7's tests) using inverse probability weighting. Inverse probability weights were multiplied by MHAS survey weight to account for complex survey design.

resultsVisual scanning ability within the lowest quartile was associated with an increased risk of recurrent falls over 3 years of follow-up (adjusted OR 1.36, 95% CI: 1.02-1.80). Associations with incident falls and falls with injury attenuated after covariate adjustment.

conclusionsPeople with lower levels of visual scanning behavior were more likely to suffer recurrent falls over time. This highlights the importance of visual function and behavior in mitigating fall risk and suggests that efforts to improve visual scanning may help to prevent recurrent falls in older adults.
