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.PURPOSE: The evaluation of syncope is often disorganized and ineffective. The objective of this study was to examine whether implementation of a standardized emergency department (ED) protocol improves the quality of syncope evaluation.

ABSTRACT.MATERIALS AND METHODS: This study was a prospective, non-randomized study conducted at a 1900-bed, tertiary teaching hospital in South Korea. We compared two specific periods, including a 12-month observation period (control group, January-December 2009) and a 10-month intervention period after the implementation of standardized approaches, comprising risk stratification, hospital order sets and establishment of a syncope observational unit (intervention group, March-December 2010). Primary end points were hospital admission rates and medical costs related to syncope evaluation.

ABSTRACT.RESULTS: A total of 244 patients were enrolled in this study (116 patients in the control group and 128 patients in the intervention group). The admission rate decreased by 8.3% in the intervention group (adjusted odds ratio 0.31, 95% confidence interval 0.13-0.70, p=0.005). There was a cost reduction of about 30% during the intervention period [369000 Korean won (KRW), interquartile range (IQR) 240000-602000 KRW], compared with the control period (542000 KRW, IQR 316000-1185000 KRW). The length of stay in the ED was also reduced in the intervention group (median: 4.6 hours vs. 3.4 hours).

ABSTRACT.CONCLUSION: Standardized approaches to syncope evaluation reduced hospital admissions, medical costs and length of stay in the overcrowded emergency department of a tertiary teaching hospital in South Korea.

Findings:
[["Educational program and ED protocol for syncope evaluation", "No standardized guidelines or educational programs", "Admission rate", "significantly decreased", "The admission rate decreased by 8.3% in the intervention group (adjusted odds ratio 0.31, 95% confidence interval 0.13-0.70, p=0.005)."]]
