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 6 finding(s) in the abstract below. Please extract them. Output only the JSON array with these 6 findings. Do not include any additional text.

Abstract:
ABSTRACT.BACKGROUND: The purpose of this study was to examine the effect of mental clinical nursing pathways on suicidal ideation and life quality of patients with malignant tumors.

ABSTRACT.METHODS: Two hundred patients with malignant tumors were randomly divided into a study group and a control group, with 100 patients in each group. During the treatment, patients in the study group received mental clinical nursing pathway care, while those in the control group were given the usual nursing care, such as timely inspection, nurse's reactions to patient's behavior, and execution of medical orders. Thereafter, the "self-rating idea of suicide scale" and Karnofsky Performance Status (KPS) were used to compare the differences in the suicidal ideation of patients with malignant tumors between the two groups before and after the treatment.

ABSTRACT.RESULTS: There were no statistical differences in the scores of despair factor, optimistic factor, sleep factor, and cover factor between the two groups before the treatment (P>0.05). After different styles of nursing, the former four factors of patients in the study group were significantly lower than those in the control group (P<0.01), while there were no significant differences in the score of cover factor between the two groups (P>0.05). The KPS of patients receiving mental clinical nursing pathway care was higher than those receiving usual nursing care, and there was a statistical significant difference between the two groups (P<0.01). Interestingly, the patients' suicidal ideation scale was negatively correlated with KPS (r =−0.29, P<0.05).

ABSTRACT.CONCLUSION: For individuals diagnosed with a malignant tumor, using a mental health clinical nursing pathway can effectively decrease the degree of suicidal ideation and positively impact the quality of life.
