Retrospective evaluation of choroidal and retinal changes in patients with diabetic peripheral neuropathy but no diabetic retinopathy.
Article in PeerJ, 2026. 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: To compare macular and choroidal findings in patients with diabetic peripheral neuropathy but no diabetic retinopathy with healthy patients. Method: We compared the ganglion cell-inner plexiform layer (GCIPL), retinal nerve fiber layer (RNFL), central macular thickness (CMT), subfoveal choroidal thickness (SFCT) and choroidal vascular index (CVI) measurements in patients with diabetic peripheral neuropathy (DPN) without diabetic retinopathy (DR) with healthy individuals. Results: Mean CMT, RNFL and SFCT values were compared in the study and control groups. There was no statistically significant difference between the groups ( Conclusion: The results obtained demonstrated a statistically significant increase in LA and TCA in the study group, although CVI remained constant. Furthermore, a statistically significant decrease in GCIPL thickness in the inferior and inferonasal sectors of the study group was identified.
