Patient and Practice Level Visual Acuity Prior to Cataract Surgery in the United States: An IRIS

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
Purpose: To examine the influence of patient demographic characteristics and ophthalmic practice composition on access to cataract surgery in the United States as measured by preoperative best-corrected visual acuity (BCVA). Patient and Methods: This retrospective cohort study analyzed data from the IRIS Results: A total of 2,387,045 individuals met the inclusion criteria. The mean BCVA prior to surgery was 0.23 (SD: 0.32) logMAR. The worst pre-operative BCVA was observed in patients with Hispanic race and ethnicity, while White patients had the best [0.34 (SD: 0.43), 0.21 (SD: 0.30); p<0.001]. Grouping patients in terms of percentage of BCVA worse than 20/50 prior to surgery, Hispanic patients, active smokers, and uninsured patients had higher percentages of worse preoperative vision (33.7%, 23.5%, 34.9%). Analysis of compositional effects of race and ethnicity, smoking, and insurance status showed that, regardless of an individual patient's demographic, patients treated at practices serving higher proportions of White patients showed better BCVA (b = -0.008 per 10 percentage points, Conclusions and Relevance: Overall differences exist with regard to the visual acuity at which cataract surgery is initiated at both the level of the individual patient and the composition of the practice in which they are treated.
