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 2 finding(s) in the abstract below. Please extract them. Output only the JSON array with these 2 findings. Do not include any additional text.

Abstract:
ABSTRACT.BACKGROUND:: Adherence to dietary and medication regimen plays an important role in successful treatment and reduces the negative complications and severity of the disease. Therefore, the present study aimed to investigate the effect of nurse-led telephone follow-up on the level of adherence to dietary and medication regimen among patients after Myocardial Infarction (MI).

ABSTRACT.METHODS:: This non-blinded randomized controlled clinical trial was conducted on 100 elderly patients with MI who had referred to the cardiovascular clinics in Shiraz. Participants were selected and randomly assigned to intervention and control groups using balanced block randomization method. The intervention group received a nurse-led telephone follow-up. The data were collected using a demographic questionnaire, Morisky's 8-item medication adherence questionnaire, and dietary adherence questionnaire before and three months after the intervention. Data analysis was done by the SPSS statistical software (version 21), using paired t-test for intra-group and Chi-square and t-test for between groups comparisons. Significance level was set at<0.05.

ABSTRACT.RESULTS:: The results of Chi-square test showed no statistically significant difference between the intervention and control groups with respect to their adherence to dietary and medication regimen before the intervention (P>0.05). However, a statistically significant difference was found between the two groups in this regard after the intervention (P<0.05). The mean differences of dietary and medication adherence scores between pre- and post-tests were significantly different between the two groups. Independent t-test showed these differences (P=0.001).

ABSTRACT.CONCLUSION:: The results of the present study confirmed the positive effects of nurse-led telephone follow-up as a method of tele-nursing on improvement of adherence to dietary and medication regimen in the patients with MI. <p> Trial Registration Number: IRCT201409148505N8
