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 3 finding(s) in the abstract below. Please extract them. Output only the JSON array with these 3 findings. Do not include any additional text.

Abstract:
ABSTRACT.OBJECTIVE: To evaluate the effects of canagliflozin, a sodium glucose co-transporter 2 inhibitor, on body weight in overweight and obese subjects (body mass index [BMI] ≥27 and <50 kg/m2).

ABSTRACT.METHODS: This 12-week, Phase 2b, randomized, double-blind study enrolled 376 subjects without diabetes mellitus who received canagliflozin 50, 100, or 300 mg or placebo once daily. The primary endpoint was the percent change in body weight from baseline through Week 12.

ABSTRACT.RESULTS: Canagliflozin increased urinary glucose excretion in a dose-dependent manner and produced statistically significant reductions in body weight compared with placebo (least squares mean percent changes from baseline of −2.2%, −2.9%, −2.7%, and −1.3% with canagliflozin 50, 100, and 300 mg and placebo; P < 0.05 for all comparisons). Overall adverse event (AE) rates were similar across groups. Canagliflozin was associated with higher rates of genital mycotic infections in women, which were generally mild and led to few study discontinuations. Osmotic diuresis-related AE rates were low and similar across groups.

ABSTRACT.CONCLUSIONS: In overweight and obese subjects without diabetes mellitus, canagliflozin significantly reduced body weight compared with placebo and was generally well tolerated.
