A Comparative Study between Laparoscopic Sleeve Gastrectomy and One Anastomosis Gastric Bypass on Serum Zinc Levels.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionBariatric surgery effectively induces weight loss, yet its impact on micronutrient homeostasis, particularly zinc, remains unclear. Given zinc’s essential role in wound healing, immunity, and hair growth, understanding postoperative changes is clinically relevant. This study evaluated the effect of sleeve gastrectomy and one-anastomosis gastric bypass on serum zinc levels.
methodsThe prospective cohort study recruited 50 patients with severe obesity who underwent bariatric surgery. Patients were divided to two groups and monitored for one year. Laparoscopic sleeve gastrectomy group included 25 participants; one anastomosis gastric bypass surgery group included 25 participants. Primary outcome was the assessment of serum zinc levels at 3, 6, and 12 months postoperatively. Secondary outcomes included the incidence of symptoms associated with reduced zinc levels, such as hair loss, diarrhea, and delayed wound healing.
resultsPatients who underwent one-anastomosis single bypass surgery had a higher incidence of low serum zinc levels at 6 months and at 12 months postoperatively compared to those who underwent sleeve gastrectomy (60.5 ± 20.9 vs. 79.8 ± 19.1 µg/dL, p = 0.008, and 49.7 ± 19.1 vs. 79.2 ± 22.8 µg/dL, p < 0.001). Symptoms related to hypozincemia, including hair loss, diarrhea and delayed wound healing, were significantly increased after one-anastomosis single bypass surgery (p ˂ 0.05).
conclusionOne-anastomosis single bypass is associated with a higher postoperative incidence of hypozincemia, as well as a worsening of symptoms compared to sleeve gastrectomy.
