Aqueous humor and serum levels of 4-hydroxynonenal and 8-hydroxy-2'deoxyguanosine in pseudoexfoliation syndrome and glaucoma.
Article in International ophthalmology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeTo compare the aqueous humor (AH) and serum levels of 4-hydroxynenal (4-HNE) and 8-hydroxy-2'-deoxyguanosine (8-OhdG) in patients with pseudoexfoliation syndrome (PES) and pseudoexfoliation glaucoma (PEG) with each other and with age- and sex-matched control group.
methodsThis prospective study included 66 patients divided into three groups: PES (n = 24), PEG (n = 21), and a control group (n = 21). 4-HNE and 8-OhdG levels were analyzed using the enzyme-linked immunosorbent assay.
resultsAqueous and serum 4-HNE levels were significantly higher in the PEG (466.52 ± 62.12 pg/mL and 313.47 ± 47.41 pg/mL) and PES (290.69 ± 63.63 pg/mL and 201.53 ± 39.57 pg/mL) groups than the control group (144.02 ± 39.58 pg/mL and 99.10 ± 16.96 pg/mL; p < 0.001, for all). Both aqueous and serum levels of 4-HNE in the PEG group were significantly higher than in the PES group (p < 0.001, for both). Similar to 4-HNE, the AH 8-OhdG levels were higher in the PEG group (21.18 ± 2.23 ng/mL) compared to the PES (14.90 ± 3.37 ng/mL) and control (4.86 ± 1.94 ng/mL) groups (p < 0.001, for all). Serum 8-OhdG levels were significantly higher in the PEG and PES groups than the control (p < 0.001, for both); however, there was no significant difference between the PES and PEG groups (p = 0.097). There were strong significant correlations between the aqueous and serum levels of 4-HNE (p < 0.001, r = 0.857) and 8-OhdG (p < 0.001, r = 0.807) among all the patients.
conclusionsAqueous humor and serum levels of 4-HNE and 8-OhdG increased in the PES and PEG patients. These findings are potentially significant and add to the growing body of evidence concerning oxidative stress in PES and PEG.
