RiMini Trial: BMI and Weight Loss Outcomes After Bariatric Surgery

Body mass index (BMI) and weight loss data from a single-center randomized controlled trial comparing ring-augmented and conventional one-anastomosis gastric bypass (OAGB). The dataset includes 214 patients, with outcomes measured at 4 months and 1 year post-surgery. It was authored by Maureen Tissink and published on figshare in 2026.

Use Cases

• Compare short-term weight loss efficacy between ring-augmented and conventional OAGB based on BMI and %TWL/%EWL metrics.
• Analyze peri-operative safety profiles of different bariatric surgery techniques based on complication rates.
• Model patient weight trajectories after surgery using BMI measurements at two time points.
• Assess the impact of surgical procedure duration on postoperative outcomes based on the reported operation times.

Strengths

• Data originates from a randomized controlled trial (RCT) with 214 patients, providing a structured study design.
• Includes specific, reported metrics such as mean BMI (28 kg/m²) and weight loss percentages (%TWL 33% vs 31%).
• Released under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset is very small at 5.5 KB, indicating limited scope and number of variables.
• Data is from a single-center trial, which may limit generalizability of findings.
