You will be shown the abstract of a medical clinical trial report. Your task is to extract all the findings from this report into a JSON array. Each finding should contain the following five elements:

- Intervention: The medical intervention being tested. This should be a text span copied from the input passage.
- Comparator: The baseline against which the intervention is being evaluated. This should be a text span copied from the input passage. If no comparator is reported, set to `null`.
- Outcome: The medical outcome whose effect is being measured. This should be a text span copied from the input passage.
- Effect: The effect of the intervention on the outcome, relative to the comparator. The effect should be one of the following three values: ("significantly increased", "significantly decreased", "no significant difference").
- Evidence: The evidence for the effect. This should be a text span copied from the input passage.

Please format your output as a JSON array. Each entry in the output should be an array containing the 5 elements listed above, in the following order: [<intervention>, <comparator>, <outcome>, <effect>, <evidence>].

For example, an output with two findings might read:
```
[["aspirin", "placebo", "headache severity", "significantly decreased", "Mean headache severity was significantly decreased in the aspirin group compared to the placebo group (p < 0.05)."], ["aspirin", "placebo", "weight loss", "no significant difference", "We did not observe any difference in weight loss between the group given aspirin relative to the control group"]]
```

There are 3 finding(s) in the abstract below. Please extract them. Output only the JSON array with these 3 findings. Do not include any additional text.

Abstract:
ABSTRACT.OBJECTIVES:: To compare the use of solifenacin and fesoterodine in treatment of overactive bladder (OAB).

ABSTRACT.METHODS:: This prospective study was conducted on patients diagnosed with OAB who presenting to the Department of Obstetrics and Gynecology and Urology, School of Medicine, Kahramanmaraş Sütçü İmam University, Kahramanmaraş, Turkey between October 2013 and August 2014. Patients were randomized into 2 groups. Group 1 (n=60) received 5 mg solifenacin per day, while Group 2 (n=59) received 4 mg fesoterodine per day. All the patients' OAB symptom scores (OABSS) in weeks 0, 4, and 12 were recorded. In addition, treatment costs and side effects of the drugs were evaluated.

ABSTRACT.RESULTS:: Average OABSS (score 1) was determined as: 9.5 ± 2.8 for Group 1 and 10.7 ± 1.8 for Group 2 at week 0; 2.2 ± 1.2 (Group 1) and 2.4 ± 1.3 (Group 2) at week 4 (score 2); and 1.3 ± 0.5 for Group 1 and 1.3 ± 0.6 for Group 2 at week 12 (score 3). In addition, no statistically significant difference was found between the scores (p=0.062 (score 1), p=0.464 (score 2), and p=0.527 (score 3). The discontinuation rate of medication due to its side effects was 0 (0%) for Group 1, and 6 (10.2%) for Group 2. Intragroup changes in the scores 1-2, 1-3, and 2-3 values was statistically significant in both groups (p<0.001).

ABSTRACT.CONCLUSION:: No significant difference was found between the OABSS of these 2 drugs. However, discontinuation of drugs due to side effects was more frequent in fesoterodine.
