Prevalence of Postoperative Micronutrient Deficiencies in Bariatric Surgery Patients Who Use Transdermal Patches for Supplementation: A Pilot Study.
Article in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 Patients require vitamin and mineral supplementation after bariatric surgery to prevent the development of micronutrient deficiencies. Consuming oral supplements is challenging due to gastric volume restriction. A transdermal patch dosage form may provide adequate micronutrient supplementation without pill burden. The study aims to determine the percentage of patients who have two or more nutritional deficiencies one year after surgery and to determine serum nutrient concentrations and gastrointestinal symptoms over time. Methods Patients who planned to undergo bariatric surgery and preferred transdermal patches versus oral supplements were recruited during preoperative office visits. Enrolled patients were instructed to use a transdermal multivitamin patch as per the manufacturer's instructions. Serum nutrient concentrations and Gastrointestinal Symptom Response Scale scores were determined at baseline and three months, six months, and one year after surgery. Results Ninety-two participants completed the study protocol. Twenty-five participants had a full panel of study labs one year after surgery. Among these patients, 19% had two or more micronutrient deficiencies. Vitamin D was the most common deficiency followed by vitamin B6; however, median serum concentrations of both nutrients increased over time. Vitamin B1, folate, and zinc deficiencies were also observed. There were no changes in gastrointestinal symptoms. Conclusions Additional studies, including randomized controlled trials, are required to determine if the PatchMD Multivitamin Plus patch (Pilot Rd. STE. B, Las Vegas) can provide adequate supplementation of vitamins and minerals. The patch was not associated with changes in gastrointestinal symptoms.
