The Diagnostic Utility of Flow Cytometry in Celiac Disease Presented Isolated Iron Deficiency Anemia.

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
backgroundFlow cytometric analysis of intestinal intraepithelial lymphocytes contributes to the diagnosis of celiac disease. Celiac disease may present with iron deficiency anemia alone which is considered as one of the forms of atypical celiac disease. In this study, we have aimed to investigate the diagnostic utility of flow cytometric analysis of intraepithelial lymphocytes in this atypical form.
methodsThree groups were formed: the patients with unexplained iron deficiency (group 1), the patients with celiac disease (group 2), and the patients who underwent gastroduodenoscopy for other reasons (group 0). Duodenal biopsy samples were used for flow cytometric analysis of intraepithelial lymphocytes. T cell receptor gammadelta intraepithelial lymphocytes and CD3-/CD103+ intraepithelial lymphocytes were determined with relevant monoclonal antibodies. Sensitivity-specificity calculation was performed to evaluate the usability of flow cytometric variables as diagnostic tests.
resultsGroup 1 had 22 patients, group 2 had 14 patients, and group 0 had 56 patients. In the comparison of the 3 groups, CD3+/ TCRγδ+ intraepithelial lymphocytes were found to be higher in celiac patients than other cases. CD3+/TCRγδ+ intraepithelial lymphocyte was evaluated for its usability as a diagnostic test. The cut-off value of CD3+/TCRγδ+ intraepithelial lymphocyte as 16.39% according to receiver operating characteristics curve analysis determined celiac disease in 14 of 22 patients in group 1 with 91.7% sensitivity and 80.4% specificity.
conclusionsAlthough celiac disease is diagnosed with serologic tests and histologic examination, successively, the increase in intestinal CD3+/TCRγδ+ intraepithelial lymphocytes may be used as a diagnostic test, and it may assist in revealing atypical forms of celiac disease.
