A comparative study of 576 patients submitted to sleeve gastrectomy or Roux-en-Y gastric bypass, evaluating hemoglobin, iron, ferritin, zinc, and vitamin B12 serum levels. Data includes measurements from the preoperative period and at three, six, 12, and 24 months post-surgery. The study was authored by Álvaro Antônio Bandeira Ferraz.
Use Cases
- Compare prevalence of hemoglobin deficiency between surgical groups based on longitudinal serum level data.
- Analyze iron and zinc deficiency trends over a 24-month postoperative period.
- Model risk factors for specific micronutrient deficiencies following different bariatric techniques.
- Benchmark postoperative nutritional outcomes for sleeve gastrectomy versus gastric bypass.
Strengths
- Study includes 576 patient records with 338 in the SG group and 238 in the RYGB group.
- Longitudinal data collected at five time points: preoperative, 3, 6, 12, and 24 months post-surgery.
- Analysis compares five specific micronutrient deficiencies (hemoglobin, iron, ferritin, zinc, B12) with reported p-values.
Limitations
- Row count and column-level documentation for the underlying dataset are unknown.
- Description metadata is limited; actual data quality requires manual inspection after download.
- Geographic origin and potential demographic biases of the patient cohort are not specified.
