Vitamin concentrations 5 years after gastric bypass.
Article in European journal of clinical nutrition, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
BACKGROUND/
objectivesFew studies have investigated the effects of bariatric surgery on vitamin status in the long term. We examined changes in vitamin status up to 5 years after Roux-en-Y gastric bypass surgery. SUBJECTS/
methodsUsing a retrospectively maintained database of patients undergoing weight loss surgery, we identified all patients operated with Roux-en-Y gastric bypass at our tertiary care hospital during July 2004-May 2008. Data on vitamin concentrations and patient-reported intake of dietary supplements were collected up to July 2012. Linear mixed models were used to estimate changes in vitamin concentrations during follow-up, adjusting for age and sex. All patients were recommended daily oral multivitamin, calcium/vitamin D and iron supplements and 3-monthly intramuscular B-12 after surgery.
resultsOut of the 443 patients operated with gastric bypass, we included 441 (99.5%) patients with one or more measurements of vitamin concentrations (75.1% women; mean age 41.5 years, mean body mass index 46.1 kg/m(2) at baseline). At 5 years after surgery, the patients' estimated mean vitamin concentrations were either significantly higher (vitamin B-6, folic acid, vitamin B-12, vitamin C and vitamin A) or not significantly different (thiamine, 25-hydroxyvitamin D and lipid-adjusted vitamin E) compared with before surgery. Use of multivitamin, calcium/vitamin D and vitamin B-12 supplements was reported by 1-9% of patients before surgery, 79-84% of patients at 1 year and 52-83% of patients 5 years after surgery.
conclusionsIn patients who underwent gastric bypass surgery, estimated vitamin concentrations were either significantly increased or unchanged up to 5 years after surgery.
