Assessing static balance control improvement following cataract surgery using a smartphone.
Article in Digital health. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Cataract remains a prevalent cause of visual impairment among the elderly, significantly increasing the risk of falls due to compromised visual function. Cataract removal surgery has been established as a means to enhance visual acuity and balance control. The advent of novel technologies, such as accelerometers integrated into smartphones, provides an opportunity to assess static balance control. We compared static balance measurements obtained from accelerometer built-in smartphones before and after cataract removal surgery. Methods: Our sample comprised 29 individuals diagnosed with bilateral cataracts scheduled for cataract removal surgery. We evaluated participants' visual acuity and recorded their body oscillations using the smartphone's embedded accelerometer during static balance maintenance, both with eyes open and closed, before and after surgery. We compared quantitative parameters of static balance evaluation at both time points. Results: A significant improvement in visual acuity following cataract removal surgery was observed. Moreover, under open-eye conditions, all quantitative parameters of static balance evaluation exhibited significant improvement, with only one parameter showing improvement under closed-eye conditions. Conclusion: Inertial sensors integrated into smartphones serve as practical tools for monitoring changes in static balance control resulting from cataracts, as well as for evaluating balance recovery after lens extraction surgery.
