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:Intravenous fluid regimen and hyponatraemia among children: a randomized controlled trial.  The aim of this study was to compare the effect of three different intravenous (i.v.) fluid regimes on the incidence of hyponatraemia in hospitalized children ranging in age from 3 months to 12 years. Children who required the administration of i.v. maintenance fluid for at least 24 h following hospitalization were eligible for inclusion. The children were randomized to three i.v. fluid groups: Group A, 0.9% saline in 5% dextrose at the standard maintenance rate; Group B, 0.18% saline in 5% dextrose at the standard maintenance rate; Group C, 0.18% saline in 5% dextrose at two-thirds of the standard maintenance rate. The primary outcome measure was incidence of hyponatraemia (plasma sodium < 130 mEq/L). Of the 167 patients enrolled, 58, 56 and 53 patients were randomized to Group A, B and C, respectively. We observed that 14.3% (8/56) of the children administered 0.18% saline in 5% dextrose at the standard maintenance rate (Group B) developed hyponatraemia compared with 1.72% of the children in Group A and 3.8% of those in Group C. Based on these results, we conclude that the administration of 0.9% saline in 5% dextrose as i.v. maintenance fluid helps in reducing the incidence of hospital-acquired hyponatraemia among children.
