Thiamine deficiency in US veterans with obesity.

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
introductionThiamine deficiency is common after bariatric surgery, but patients with obesity may be deficient in thiamine even before surgery. The purpose of this research was to determine the prevalence of thiamine deficiency in patients with obesity at a medical weight-management clinic and assess the relationship between recent weight loss and thiamine deficiency.
methodsFor this observational study, medical records were reviewed for patients (n = 146) at the nonsurgical obesity medicine and preoperative bariatric surgery clinic at a Veterans Affairs Medical Center between January 1, 2012, and January 31, 2019. Thiamine deficiency was defined as a value less than the test reference range. χ
resultsThiamine deficiency was found in 32.2% of patients. There were no differences in the prevalence of deficiency by gender, race, or type 2 diabetes status. Weight loss was associated with increased risk for deficiency, although this was not statistically significant (odds ratio = 2.04, 95% CI: 0.79-5.27).
conclusionsApproximately one-third of patients evaluated had a test result indicating thiamine deficiency. All people with obesity may benefit from additional nutritional screening.
