Ratio of hemoglobin to mean corpuscular volume: A new index for discriminating between iron deficiency anemia and thalassemia trait.
Article in World journal of clinical cases, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIron deficiency anemia (IDA) and thalassemia trait (TT) are the most common microcytic and hypochromic anemias. Differentiation between mild TT and early IDA is still a clinical challenge.
aimTo develop and validate a new index for discriminating between IDA and TT.
methodsBlood count data from 126 patients, consisting of 43 TT patients and 83 IDA patients, was retrospectively analyzed to develop a new index formula. This formula was further validated in another 61 patients, consisting of 48 TT patients and 13 IDA patients.
resultsThe new index is the ratio of hemoglobin to mean corpuscular volume. Its sensitivity, specificity, accuracy, Youden's Index, area under the receiver operating characteristic curve, and Kappa coefficient in discriminating between IDA and TT were 93.5%, 78.4%, 83.3%, 0.72, 0.97, and 0.65, respectively.
conclusionThis new index has good diagnostic performance in discriminating between mild TT and early IDA. It requires only two results of complete blood count, which can be a very desirable feature in under-resourced scenarios.
