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 1 finding(s) in the abstract below. Please extract them. Output only the JSON array with these 1 findings. Do not include any additional text.

Abstract:
ABSTRACT.BACKGROUND:: Family-centered empowerment of drug and stimulant users is an effective program for a better response to treatment, prevention of treatment adverse effects, and promotion quality of life (QoL) and lifestyle in the process of discontinuing drug abuse.

ABSTRACT.OBJECTIVES:: This study aimed to determine the effects of educational intervention, based on family-centered empowerment and Pender's health promotion models, on health-promoting lifestyle and health-related QoL among methamphetamine users and their families.

ABSTRACT.PATIENTS AND METHODS:: In a randomized clinical trial, methamphetamine users, who were admitted to Tehran University of Medical Sciences Substance Abuse Treatment Centers, were randomly allocated to three groups: a group for training of methamphetamine users who were in recovery phase (intervention group 1;95 subjects);a group for training of a family member of methamphetamine users who were in recovery phase (intervention group 2; 95 subjects); and a control group (95 subjects). A demographic checklist and a standard questionnaire covering health-promoting lifestyle, health-related QoL, self-efficacy, perceived affect, perceived social support, and perceived barriers dimensions were used to gather required data. Independent-samples t test, paired-samples t-test, and ANCOVA were used to analyze the data.

ABSTRACT.RESULTS:: Analysis of covariance showed that after adjusting for effects of pretest scores, the difference between mean post-test scores of health-promoting lifestyle scale, health-related QoL scale, and all constructs of Pender's health promotion model (self-efficacy, perceived affect, perceived social support, and perceived barriers) in the intervention group 1 and control group were significant (P< 0.0001). In addition, changes in mean scores of lifestyle scale (42.4 ± 13.6), QoL scale (29.1 ± 14.2), self-efficacy (16.1 ± 2.6), perceived affect (16.1 ± 8), social support (35.4 ± 12.4), and barriers (17.2 ± 15.8) before and after intervention were significant in the intervention group 2 (P < 0.0001).

ABSTRACT.CONCLUSIONS:: Application of family-centered empowerment model among methamphetamine users and their families is practically feasible and can result in enhancement and improvement of their QoL, lifestyle, and health promotion model constructs.
