The Effect of Laparoscopic Sleeve Gastrectomy on Serum Levels of Vitamin A, D and B12 and Iron Profile on Patients with Morbid Obesity.

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
Background: One of the concerns after bariatric surgery is the lack of nutrients and vitamins due to anatomical and physiological changes that occur after the surgery. The aim of the present study is to evaluate the effect of laparoscopic sleeve gastrectomy on these nutrients and vitamins. Materials and Methods: This prospective study was performed in Tehran and all the patients who met the inclusion criteria before the surgery were tested for serum levels of vitamins A, B12, D, ferritin, serum iron, and TIBC. The patients were tested once again for the same micronutrients, one year after surgery. Results: A total of 120 patients had the inclusion criteria and all of them completed the follow-up period. Of the patients, 64.2% (77 patients) were female and 35.8% (43 patients) were male. The mean weight of the patients was 122.1 ± 14.8 kg and the mean BMI of patients before surgery was 43.6 ± 4.4 kg/m Conclusion: The result of the present study demonstrated that laparoscopic sleeve gastrectomy is one of the most effective surgical methods for obesity treatment and does not cause a lack of nutrients and vitamins in long term and does not require supplementation. In addition, it promotes serum levels of vitamin D, which is effective in preventing the effects of vitamin D deficiency in obese patients.
