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
Introduction: Cardiovascular diseases are common complications in chronic kidney disease (CKD). Oxidative stress associated with renal and metabolic dysfunctions is one of the cardiovascular complications (CVC) in haemodialysis patients. The aim of the present study is to analyse the oxidative stress markers in CDK patients supplemented with antioxidants and vitamin E, with monitoring of CVC. Material and methods: This was a cross-sectional study conducted on 99 subjects. CKD patients received oral supplementation of vitamin E (300 mg/day) for 2 years. Oxidative stress markers, nitric oxide (NO); myeloperoxidase (MPO); oxidized low-density lipoprotein (LDLox); malondialdehyde (MDA) and glutathione were measured before and after the vitamin treatment. Results: NO (62.62 ±2.80 μmol/l), LDLox (10.55 ±4.62 μmol/l), MDA (6.11 ±2.83 μmol/l) and MPO (53.35 ±3.82 UI/ml) were overconcentrated, while glutathione (62.09 ±4.15 UI/ml) was less concentrated in CKD patients with cardiovascular complications, compared to those without cardiovascular complications (67.08 ±1.90 μmol/l, 31.18 ±5.25 μmol/l, 16 ±6.47 μmol/l, 57.00 ±7.24 UI/ml, 43.09 ±3.33 UI/ml, respectively). After 2 years of vitamin E treatment, the overall cardiovascular complications were not significantly decreased. Conclusions: These results showed that oral complementation with vitamin E did not affect the occurrence of cardiovascular complications associated with CKD. These findings may pave the way for future innovative strategies for antioxidant supplementation in CKD patients.
