Iron Deficiency-Challenging to Diagnose: A Retrospective Chart Review of Referrals to Classical Hematology Clinic.
Article in Journal of community hospital internal medicine perspectives, 2025. 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
Background: Iron deficiency (ID) is the leading nutritional deficiency and a major public health concern globally. Although anemia is the most widely known consequence of ID, ID is also an underrecognized cause of white blood cell and platelet count abnormalities. The primary objective of the current study is to assess physicians' abilities to diagnose ID. Methods: This study is a retrospective chart review of 862 adults (mean age ± SD of 52.5 ± 18.4, 447 female) seen by a classical hematologist at an academic center. Data analysis included specialty type of the referring provider, referral reason, and the diagnosis made by the consulting hematologist. ID was defined as a serum ferritin level <30 ng/mL or <100 ng/mL in the presence of inflammatory comorbidities. Results: Out of 862 initial patient charts, 103 were lost to follow up before completing the workup. Out of the remaining 759 patient charts, 304 (40.0 %) patients received a new diagnosis with ID or iron deficiency anemia (IDA) by the consulting classical hematologist. Of these patients, 21 % were referred from internal medicine (IM), 18 % from family medicine (FM), 14 % from hematology-oncology for a second opinion, and 25 % from other IM subspecialties. In a sub-analysis of 364 patients who had complete blood cell count (CBC) abnormalities, ID was found to play a role in 54.7 % of CBC abnormalities analyzed. Conclusion: This analysis demonstrates that diagnosing ID is a challenge for first-contact physicians and may easily be missed. This leads to delays in ID treatment and resulting clinical consequences.
