Impact of systemic hypertension on inner retinal layer thickness and macular microvasculature in patients with diabetic retinopathy.
Article in Acta diabetologica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
aimTo investigate the effects of hypertension (HTN) on inner retinal thickness and macular microvasculature in patients with diabetic retinopathy (DR).
methodsSubjects were classified into three groups: patients with type 2 diabetes mellitus (T2DM) (T2DM group), patients with DR (DR-HTN group), and patients with DR and HTN (DR + HTN group). The ganglion cell complex (GCC) thicknesses and the macular vessel density (VD) were compared. Linear regression analyses were performed to identify factors associated with the VD in the DR + HTN group.
resultsThe mean GCC thicknesses were 112.2 ± 12.3, 109.2 ± 13.7, and 106.2 ± 11.2 μm in the T2DM, DR-HTN, and DR + HTN groups, respectively (P = 0.045). The mean VDs were 25.4 ± 5.0, 24.3 ± 8.9, and 21.2 ± 7.1% (P = 0.014) for the superficial capillary plexus (SCP) and 25.9 ± 4.3, 22.9 ± 8.5, and 20.2 ± 6.6% (P < 0.001) for the deep capillary plexus (DCP) in the T2DM, DR-HTN, and DR + HTN groups, respectively. In multivariate analyses, the duration of HTN was a significant factor associated with the VD of both SCP (B = -0.24, P = 0.010) and DCP (B = -0.21, P = 0.016).
conclusionsPatients with both DR and HTN had a thinner GCC and lower VDs of SCP and DCP than those with DR alone. These outcomes could be associated with the synergistic ischemic effects in DR patients with HTN. Moreover, the duration of HTN in DR patients was significantly associated with macular VD in both SCP and DCP.
