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 5 finding(s) in the abstract below. Please extract them. Output only the JSON array with these 5 findings. Do not include any additional text.

Abstract:
ABSTRACT: [Purpose] The aim of the present study is to examine the effects of silver spike point
therapy on elderly persons' chronic constipation. [Subjects and Methods] The subjects of
the present study were 30 elderly chronic-constipation sufferers who resided in a nursing
home and had other physical conditions that necessitated wheelchair ambulation. There were
three test groups in the present study: an silver spike point group, an acupuncture group,
and a control group; 10 subjects were assigned to each group. The silver spike point group
and the acupuncture group received their respective interventions, which were applied to
both sides of the Tiensu for 20 minutes per day, five days per week, over a four week
period. Weekly bowel movement frequency was recorded, and the Constipation Assessment
Scale and Bowel Function Assessment Form were used as data-gathering instruments.
[Results] Following treatment, the silver spike point and acupuncture groups showed
significant improvement, based on the Constipation Assessment Scale and the Bowel Function
Assessment Form, compared with the control group. [Conclusion] Based on the above results,
silver spike point therapy can be administered to alleviate chronic constipation in
elderly nursing home residents who cannot walk independently due to declining physical
functions.
