Diagnostic utility of low hemoglobin density to detect iron deficiency in patients with inflammatory bowel disease.
Article in Annals of gastroenterology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIn the absence of a feasible noninvasive gold standard, iron deficiency (ID) anemia (IDA) is best measured using multiple indicators. However, the choice of an appropriate single iron biomarker for ID screening continues to be debated. Low hemoglobin density (LHD%) from Coulter counters has been suggested as a useful tool to detect ID. This study investigated the reliability of LHD% for the assessment of iron status in patients with inflammatory bowel disease (IBD) and IDA, anemia of chronic disease (ACD) or mixed anemia (MIX).
methodsThe study population consisted of 143 patients with IBD (aged 39.03±12.53 years, 61.5% female). Blood count, transferrin saturation, serum ferritin, and C-reactive protein were determined by routine assays. Patients with anemia were divided into 3 groups: IDA, ACD and MIX, according to specific criteria. Receiver operator characteristic (ROC) curves were constructed.
resultsROC analysis for LHD% in the detection of ID yielded a cutoff value of 3.8%. In anemic patients, LHD% values did not differ statistically significantly between groups (IDA, ACD, MIX) and no significant difference in LHD% values was observed between patients with IDA and ID.
conclusionsThese results demonstrate that LHD% is a reliable biomarker for the detection of iron deficiency in patients with IBD and anemia, regardless of whether inflammation is present. Our findings indicate that LHD% can provide added value in diagnosing iron deficiency.
