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 4 finding(s) in the abstract below. Please extract them. Output only the JSON array with these 4 findings. Do not include any additional text.

Abstract:
ABSTRACT.BACKGROUND: Older adults are more vulnerable to health risks than younger people and may get exposed to various dangers, including elder abuse. This study aimed to design and implement an empowerment educational intervention to prevent elder abuse.

ABSTRACT.METHODS: This parallel randomized controlled trial was conducted in 2014–2016 for 18 months on 464 older adults aged above 60 years who visited health houses of 22 municipalities in Tehran. Data were collected using standard questionnaires, including the Elder Abuse-Knowledge Questionnaire, Health-Promoting Behavior Questionnaire, Health-Promoting Lifestyle Profile II, Barriers to Healthy Lifestyle, Perceived Social Support, Perceived Self-Efficacy, Loneliness Scale, Geriatric Depression Scale, Multidimensional Health Locus of Control Scale, and the SCARED (stress, coping, argument, resources, events, and dependence) tool. The intervention was done in twenty 45- to 60-minute training sessions over 6 months. Data analysis were performed using χ2 tests, multiple linear and logistic regression, and structural equation modeling (SEM).

ABSTRACT.RESULTS: The frequency of knowledge of elder abuse, self-efficacy, social support and health promoting lifestyle before the intervention was similar in the two groups. However, the frequency of high knowledge of elder abuse (94.8% in the intervention group and 46.6% in the control group), high self-efficacy (82.8% and 7.8%, respectively), high social support (97.0% and 10.3%, respectively) and high health promoting lifestyle (97.0% and 10.3%, respectively) was significantly higher (P<0.001) and the frequency of elder abuse risk (28.0% and 49.6%, respectively) was significantly less in the intervention group after the intervention. SEM standardized beta (Sβ) showed that the intervention had the highest impact on increase social support (Sβ=0.80, β=48.64, SE=1.70, P<0.05), self-efficacy (Sβ=0.76, β=13.32, SE=0.52, P<0.05) and health promoting behaviors (Sβ=0.48, β=33.08, SE=2.26, P<0.05), respectively. The effect of the intervention on decrease of elder abuse risk was indirect and significant (Sβ=−0.406, β=−0.340, SE=0.03, P<0.05), and through social support, self-efficacy, and health promoting behaviors.

ABSTRACT.CONCLUSION: Educational interventions can be effective in preventing elder abuse.
