The association of cataract surgery with risk of falls and fractures among Medicare enrollees with cataract.

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
backgroundFalls and fractures are a significant public health concern linked to visual impairment. Cataracts are the most common cause of visual impairment in older adults and can be corrected with cataract surgery. This study evaluated whether cataract surgery reduces the one-year risk of falls/fractures in Medicare beneficiaries with cataract.
methodsUsing 2019-2021 claims data from a nationally representative cohort of 940 233 Medicare fee-for-service enrollees (66+ years), we identified those with untreated cataract in 2019 and grouped them into those with and without cataract surgery in 2020. Using the surgery date (surgery group) or a randomly assigned date in 2020 (non-surgery group) as the index date, we identified incident falls/fractures (outpatient, emergency department, or inpatient) during the following 365 days. We used a propensity score-based (with average treatment effect on the treated weights) linear probability regression model to estimate the association of cataract surgery with the risk (likelihood) of falls/fractures, accounting for observed differences between those with and without surgery.
resultsWithout surgery, the estimated likelihood of falls/fractures was 8.86% (95% CI, 8.53-9.18%). Cataract surgery was not associated with a significant difference in the risk of falls/fractures (risk difference = -0.15 percentage points; 95% CI, -1.0, 0.74). Similar findings were observed for subgroups by race and ethnicity, frailty, and fall/fracture history.
conclusionsCataract surgery was not significantly associated with one-year risk of falls/fractures in Medicare beneficiaries. Future studies should evaluate fall risk over a longer follow-up period or the impact of surgery on self-reported falls not captured by the healthcare system.
