Does Bariatric Surgery Cause Vitamin A, B1, C or E Deficiency? A Systematic Review.
Synthesis in Obesity surgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers, 2 of them syntheses that pooled it.
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
backgroundThe restrictive and/or malabsorptive nature of bariatric surgery may increase the risk for micronutrient deficiencies. This systematic review aimed to identify and critique the evidence for vitamin A, B1, C or E deficiencies associated with bariatric surgery.
methodsThis review utilised PRISMA and MOOSE frameworks with NHMRC evidence hierarchy and the American Dietetic Association bias tool to assess the quality of articles.
resultsTwenty-one articles were included and once critiqued all studies were of level IV grade and neutral or negative in quality. The relevance of measuring micronutrient supplementation and inflammatory markers for validity of serum vitamins is absent within the literature.
conclusionsFuture research is needed to investigate the risk of deficiency for these procedures with focus on confounders to serum micronutrients.
