Evaluating the Compliance, Efficacy, and Cost of Formulated Vitamins Versus Separate Supplements in Post-bariatric Surgery Patients.
Article in Obesity surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveMicronutrient deficiencies are common complications after bariatric surgery as alterations to the gastrointestinal tract change absorption. Patients are recommended to take supplements including multivitamins, B complex, calcium, vitamin D, and iron after bariatric surgery, and can take these as specifically formulated vitamins for post-bariatric patients or separate vitamin supplements. We investigated the compliance, efficacy, and cost of specifically formulated vitamins for post-bariatric patients in comparison to separate vitamin supplements.
methodsWe surveyed 126 post-bariatric adult patients between February 1, 2022, and August 31, 2022, who had undergone bariatric surgery between 2014 and 2021 to assess the type of supplements taken, compliance, and cost. Demographics, type of bariatric surgery, and serum micronutrient levels were evaluated for all patients.
resultsThere were 51 patients taking formulated vitamins and 75 patients taking separate vitamins. The formulated vitamin group demonstrated greater adherence to optimal vitamin dosage (formulated vitamin group, 76.5% vs. separate supplement group, 30.7%; p < 0.001) and higher compliance (formulated vitamin group, 90.2% vs. separate supplement group, 66.7%; p = 0.002). The costs associated with both groups were comparable. No significant difference was observed in the incidence of micronutrient deficiency between the groups.
conclusionsOur study shows that formulated vitamins do not offer significant difference in micronutrient levels or cost compared to separate standard vitamin supplements. However, formulated bariatric vitamins have improved compliance compared to separate vitamin supplements.
