Bone marrow macrophage iron content and sideroblast count in iron- and ESA-naïve patients with CKD-related anemia.
Article in Renal failure, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundSince in chronic kidney disease (CKD) iron deficiency anemia (IDA) can coexist with inflammation-induced immobilization of iron in macrophages (anemia of chronic disorders - ACD), we assessed the utility of ferritin, transferrin saturation (TSAT), and hepcidin for differentiation of mixed IDA-ACD from ACD, using bone marrow (BM) examination as reference.
methodsThis cross-sectional, single-center study analyzed 162 non-dialysis iron and epoietin-naïve CKD patients (52% males, median age 67 years, eGFR 14.2 mL/min 1.73 m
resultsACD was seen in 51%, IDA-ACD in 40%, while "pure" IDA in only 9%. In univariate and binomial analyses, IDA-ACD differed from ACD by lower ferritin and TSAT, but not by hepcidin or CRP. Correspondingly, in receiver operating curve analysis, ferritin and TSAT differentiated IDA-ACD from ACD, at cutoffs of 165 ng/mL and 14%, but with moderate precision (sensitivity and specificity of 72%, and 61%, respectively).
conclusionThe mixed pattern IDA-ACD could be more prevalent than estimated in non-dialysis CKD. Ferritin and, to a lesser degree, TSAT are useful in the diagnosis of IDA superimposed on ACD, while hepcidin, although reflecting BM macrophages iron, seems to have limited utility.
