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: Food cues of palatable food are omnipresent, thereby simulating the intake of unhealthy snack food among children. As a consequence, this might lead to a higher intake of energy-dense snacks and less fruit and vegetables, a habit that increases the risk of developing chronic diseases. The aim of this experimental study is to examine whether playing a memory game with fruit affects fruit intake among young children. We used a randomized between-subject design with 127 children (age: 7–12 y) who played a memory-game, containing either fruit (n = 64) or non-food products (n = 63). While playing the memory-game in a separate room in school during school hours, free intake of fruit (mandarins, apples, bananas, and grapes) was measured. Afterwards, the children completed self-report measures, and length and weight were assessed. The main finding is that playing a memory-game containing fruit increases overall fruit intake (P = 0.016). Children who played the fruit version of the memory-game ate more bananas (P = 0.015) and mandarins (P = 0.036) than children who played the non-food memory-game; no effects were found for apples (P > 0.05) and grapes (P > 0.05). The findings suggest that playing a memory-game with fruit stimulates fruit intake among young children. This is an important finding because children eat insufficient fruit, according to international standards, and more traditional health interventions have limited success. Healthy eating habits of children maintain when they become adults, making it important to stimulate fruit intake among children in an enjoyable way. <p> Trial registration: Nederlands Trial Register TC = 5687
