What studies found when this marker was changed
They describe what happened in those study groups, not a recommendation. See all catalogued interventions.
Measured changes in Urinary 8-oxoGuo, study by study
3 effects with a numeric size, each from one study arm: the dot is the reported change, the line its 95% interval where one was given. Study results in the groups studied, not predictions for a person.
Things that worsen it
| Type | Condition or exposure | Reported effect | Evidence | Source |
|---|---|---|---|---|
| diet | Weight-stable carbohydrate-reduced high-protein diet (30E% carbohydrate) vs conventional diabetes diet (50E%) in type 2 diabetes, randomised crossover | 24-h urinary 8-oxoGuo was 9.3% higher after 4 weeks on the carbohydrate-reduced high-protein diet than on the conventional diabetes diet (p = .03); crossover, n=30 | RCT | Skytte MJ, et al. Scand J Clin Lab Invest. 2020;80(5):401-407. |
| pharmacologic | One week of oral clarithromycin vs placebo in healthy adults (harmful exposure: raises RNA oxidation) | 24-h urinary 8-oxoGuo rose 14.9% (95% CI 3.7 to 26.1%) after 1 week of clarithromycin vs placebo in healthy adults | RCT | Larsen EL, et al. Br J Clin Pharmacol. 2017;83(8):1643-1653. |
| pharmacologic | Metformin 1000 mg twice daily vs placebo for 18 months, on top of insulin therapy, in type 2 diabetes | Urinary 8-oxoGuo rose 7.1% (95% CI 0.5 to 14.0%) with metformin vs placebo over 18 months; 415 randomised (number written out in the abstract) | RCT | Larsen EL, et al. Free Radic Biol Med. 2022;178:18-25. |
