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:Low-dose versus moderate-dose atorvastatin after acute myocardial infarction: 8-month effects on coronary flow reserve and angiogenic cell mobilisation.  To compare the effects of atorvastatin 10 mg versus 40 mg in circulating angiogenic cell mobilisations and in restoring coronary flow reserve (CFR) during the 8-month follow-up in patients with a first acute myocardial infarction (AMI). CFR was measured using an intracoronary Doppler wire in 102 patients with AMI at baseline and at 8 months. Changes in the absolute number of circulating angiogenic cells were measured at baseline, 1 day, 5 days and at 8 months. Stented patients were randomly assigned to either low-dose atorvastatin 10 mg (ATOR10, n=52) or moderate-dose atorvastatin 40 mg (ATOR40, n=50). Setting University Hospital. CFR increased significantly in both groups during the 8-month follow-up. The 8-month increases from baseline in CFR were significantly greater in the ATOR40 group than in the ATOR10 group (0.99+/-0.69 vs 0.55+/-0.47, p=0.017, respectively). The serial increases in the absolute number of CD34+ and CXCR4+ cells were significantly greater in the ATOR40 group, especially at 24 h after the procedure (two-way repeated-measures analysis of variance: p=0.046 and p=0.022, respectively). Decreases from baseline for interleukin 6 (-2.94+/-3.31 vs -1.52+/-2.82 pg/ml), tumour necrosis factor alpha (-1.31+/-2.96 vs -0.01+/-1.29 pg/ml), soluble intercellular adhesion molecule-1 (-71+/-95 vs 37+/-83 ng/ml) and soluble vascular cell adhesion molecule-1 (-51+/-364 vs 190+/-204 ng/ml) were significantly greater in the ATOR40 group. The recovery of microvascular integrity after acute ischaemic injury in the ATOR40 group was expedited by greater circulating angiogenic cell mobilisations such as CD34+ and CXCR4+ cells, together with greater decreases in inflammatory cytokines and low-density lipoprotein-cholesterol concentrations.
