1 · What the graph read from it

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.

2 · The registry

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 assess the impact of hypertension (HTN) on microvasculature and vision in clinically referable diabetic retinopathy (DR) eyes using optical coherence tomography angiography. Methods: We conducted a cross-sectional study of 185 eyes (139 patients) with referable DR (moderate/severe nonproliferative to naïve/quiescent proliferative DR), categorizing patients based on presence/absence of HTN. Optical coherence tomography angiography 3 × 3 mm scans were utilized to quantify geometric perfusion deficits (GPD), vessel length density, and vessel density within the superficial capillary plexus and deep capillary plexus (DCP). Linear regression analysis investigated the association between risk factors and GPD. Results: Our DR cohort comprised 52 nonhypertensive and 133 hypertensive eyes. After adjusting for age and dyslipidemia, we found significant differences in DCP metrics (GPD and vessel length density) between groups. The mean DCP GPD was higher in DR eyes with HTN compared with those without (7.06 ± 4.33 vs. 5.58 ± 2.85%; P = 0.032). Conversely, DCP vessel length density was lower in hypertensive DR eyes compared to nonhypertensive DR eyes (0.17 ± 0.02 mm-1 vs. 0.18 ± 0.02 mm-1; P = 0.031). Multivariable analysis confirmed a significant independent association between HTN (β = 0.250; P = 0.036) and DCP GPD. Worse vision was moderately associated with worsening DCP GPD (P < 0.001) in hypertensive DR eyes. Conclusions: In referable DR eyes, HTN is associated with worse DCP nonperfusion and compromised vision. Therefore, heightened surveillance, in addition to blood pressure control, may need to be prioritized for this high-risk population with comorbid diabetes and HTN. Translational Relevance: HTN is associated with worse vision and ischemia in the deep capillary layer of referable DR eyes, emphasizing the importance of monitoring patients with both comorbidities.
