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:Efficacy and safety of early versus late titration of fixed-dose irbesartan/hydrochlorothiazide: ACTUAL study.  Hypertension management guidelines recommend titrating antihypertensive drugs stepwise every 4-6 weeks.We compared efficacy and safety of early versus late titration after 10 weeks' treatment with irbesartan/hydrochlorothiazide. Hypertensive patients uncontrolled on monotherapy were randomized into two groups. In the early titration group (E), patients received irbesartan/hydrochlorothiazide 150/12.5 mg for 2 weeks; uncontrolled patients were up-titrated to 300/25 mg at weeks 2 and 6. In the late titration group (L), patients received 150/12.5 mg for 6 weeks; uncontrolled patients were up-titrated to 300/25 mg at week 6 (W6). The change of mean systolic (SBP) and diastolic blood pressure (DBP) from baseline to week 10 (W10) were studied using a covariance analysis model. The percentage of controlled patients at W10 was compared between groups using Fisher's exact test. Of 833 patients enrolled from 14 countries, the intent-to-treat (ITT) population included 795 (mean age 58 +/- 12 years, female 60%, obesity 38%, diabetes 22%). AtW6, mean SBP decrease was: E - 28.8 mmHg vs L - 26.3 mmHg (p = 0.02). At W10, there was similar mean SBP decrease: E - 29.5 mmHg vs L- 31.0 mmHg (p = 0.14). The control rate at W10 was 58% (E) and 64% (L), p = 0.06. Serious adverse events were more frequent in E (2.5% vs 0.7%, p= 0.044). Both early and late titration regimens provide similar BP decrease and control rate. Output:
