Serum levels of copper and zinc in diabetic retinopathy: Potential new therapeutic targets (Review).
Review in Experimental and therapeutic medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 29 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
Diabetic retinopathy (DR) is a microvascular disorder occurring due to the long-term effects of diabetes, leading to vision-threatening damage to the retina. The human body has an elaborate system for managing and regulating the number of key trace metals circulating in the blood and stored cells. Inadequate zinc (Zn) and concurrent excess of copper (Cu) levels are associated with an increased level of oxidative stress, which may aggravate the microvascular lesions in diabetes mellitus. Several studies have revealed a significantly lower serum Zn concentration and increased Cu levels in DR when compared with diabetic patients without retinopathy and normal controls. These abnormalities are correlated with the duration of diabetes and higher levels of HbA1C. Multiple pathological mechanisms are proposed to explain these changes including hyperzincuria associated with polyuria, glycosuria, and proteinuria in diabetic patients, as well as impaired absorption of Zn at the gastrointestinal level. Increased levels of free Cu ions may be attributed to glycation and the release of Cu ions from the Cu-binding sites of proteins. Zn supplements and selective Cu chelators may be useful to alleviate oxidative stress and prevent DR progression.
