Glycated Hemoglobin Improvement After Medical and Surgical Eye Care in American Veterans Involves Multidisciplinary Care.
Article in Clinical ophthalmology (Auckland, N.Z.), 2023. 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
Purpose: The effects of diabetes mellitus (DM) on visual function have been extensively studied. Fewer studies evaluate the effect of visual function on DM, and previous small studies have shown mixed results concerning the relationship between glycated hemoglobin (HbA1c) and cataract surgery. We performed a retrospective, observational, single-site study at a Veterans hospital to evaluate this relationship and the relationship between HbA1c and non-surgical eye care. Patients and Methods: We compared pre- and post-operative/examination HbA1c in 431 surgical and 431 matched, non-surgical subjects who underwent eye examination at the same institution. Subgroup analysis was performed by age, elevated (≥8) pre-operative/examination HbA1c, and change in diabetic management. We also assessed for a relationship between changes in best-corrected visual acuity (BCVA) and HbA1c. The Minneapolis Veterans Affairs Health Care System Research Administration determined this study to be Institutional Review Board exempt from the requirements of 38 CFR 16 under Category 4 (iii). Results: Pairwise comparison of pre- versus post-operative HbA1c trended towards reduction at 3-6 months in all surgical subjects, with a statistically significant reduction in older subjects, and those with higher pre-operative HbA1c. Eye examination subjects experienced a significant HbA1c reduction 3-6 months after eye examination. Reduction in post-operative/examination HbA1c was associated with concurrent change in diabetic management. Conclusion: We found an overall reduction in HbA1c in diabetic Veterans who interacted with an ophthalmologist, whether for cataract surgery or eye examination. HbA1c reduction was greatest when ophthalmic care was delivered as part of a multidisciplinary care team. Our findings add new evidence to further support the importance of ophthalmic care in patients with DM and suggest improved visual function may facilitate improved glycemic control.
