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
Objective: To investigate the association between retinal microcirculation changes, assessed using optical coherence tomography angiography (OCTA), and mild cognitive impairment (MCI) in patients with type 2 diabetes mellitus (T2DM), and to determine whether retinal microcirculation changes can serve as a potential biomarker for MCI in these patients. Methods: A total of 100 patients with T2DM who visited Hefei Aier Eye Hospital between April 2023 and December 2024 were selected. Retinal microcirculation indicators, including the perfusion density of the superficial capillary plexus (SCP), the perfusion density of the deep capillary plexus (DCP), the central foveal thickness (CMT) and the area of the foveal avascular zone (FAZ), were evaluated using OCTA. The cognitive function of the patients was assessed using the Montreal Cognitive Assessment. The association between retinal microcirculation indicators and MCI was explored using multivariate logistic regression analysis. Results: The perfusion density of SCP and DCP in all patients was lower than the normal value. Patients with CMT outside the normal range accounted for 73%, and those with FAZ outside the normal range accounted for 23%. No significant correlation was found between individual retinal microcirculation indicators and MCI. However, a significant association was observed when the four indicators were combined ( Conclusion: Retinal microcirculation changes based on OCTA are significantly associated with MCI in patients with T2DM, suggesting that retinal microcirculation indicators may serve as potential biomarkers for MCI in these patients.
