Prevalence of Micronutrient Deficiency in Patients with Morbid Obesity Before Bariatric Surgery.

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
backgroundPostoperative micronutrient deficiency is a known side effect of bariatric surgery. In this study, we examined the prevalence of micronutrient deficiency in patients with morbid obesity (MO) preoperatively.
methodsA total of 1732 patients with MO wishing to undergo bariatric surgery (age: 40 ± 12 years, mean BMI: 44 ± 9 kg/m
resultsA total of 63.2% (n = 1094) of the patients had a deficit in folic acid (< 5.3 ng/ml), 97.5% (n = 1689) in 25OHvitamin D (< 75 nmol/l), and 30.2% (n = 523) had a PTH elevation (> 56.9 pg/ml). A total of 5.1% (n = 88) of the patients presented with a deficit in vitamin B12 (< 188 pg/ml) and 6.2% (n = 107) in vitamin A (< 1.05 μmol/l). A total of 9.6% (n = 166) exhibited iron deficiency (ferritin < 15 μg/l). None of the patients had a deficit in vitamin E. There were no gender differences except for ferritin deficiency (women 11.8% vs. men 1.5%, p < 0.001). Patients in the highest BMI tertile had significantly more often a deficit in vitamin D (p = 0.033) and folic acid (p < 0.001). Patients in the lowest age tertile had significantly more often a deficit in folic acid (p < 0.001).
conclusionsOur data show a high prevalence of micronutrient deficiency in patients with morbid obesity preoperatively and emphasize the importance of exact preoperative evaluation and adequate substitution as well as postoperative surveillance.
