Your goal is to extract structured information from the user's input that matches the form described below. When extracting information please make sure it matches the type information exactly. Do not add any attributes that do not appear in the schema shown below.

```TypeScript

 { // Information on the clinical trial characteristics from the abstract
 conditions: string // The condition or disease being treated in the clinical trial
 drug_or_intervention: string // The drug or intervention used in the clinical trial
}
```


Please output the extracted information in JSON format. Do not output anything except for the extracted information. Do not add any clarifying information. Do not add any fields that are not in the schema. If the text contains attributes that do not appear in the schema, please ignore them. All output must be in JSON format and follow the schema specified above. Wrap the JSON in <json> tags.



Input:Antioxidant supplementation in pregnant women with low antioxidant status.  The aim of this study was to investigate the benefit of antioxidant supplementation in a cohort of women with low antioxidant status and determine the changes in cell-free mRNA. This study was a randomized, placebo-controlled trial of 8-12 weeks' pregnant women who had low antioxidant status treated with either antioxidants or control diets daily until 2 weeks' postpartum. The primary end-point was the risk of pre-eclampsia and the secondary end-point was the changes of angiogenic and anti-oxidant mRNA markers related to the outcome (ClinicalTrial.gov, number NCT01232205). There were 110 women enrolled in the study, randomly assigned to the supplementation (n = 52) and control group (n = 58). The overall rate of pre-eclampsia was 8.7% (nine subjects). There were significant differences (P = 0.034) between the supplementation and control group in the incidence of pre-eclampsia (2.0% [one case] and 14.5% [eight cases], respectively) and mRNA level of superoxide-dismutase, heme oxygenase-1, vascular endothelial growth factor receptor-1, endoglin and placental growth factor after supplementation. Supplementation of women with low antioxidant status with micronutrients containing antioxidants during early gestation might reduce the risk of pre-eclampsia. Output:
