The Impact of Anemia on the Survival of Patients Diagnosed With Low-Grade Malignant B-cell Lymphomas.
Article in Cureus, 2024. 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
introductionB-cell lymphomas with a low degree of malignancy represent a heterogeneous group of diseases, that evolve slowly, but present particularities in terms of long-term survival.
methodsWe investigated the impact of anemia from the time of diagnosis in 249 patients with malignant B-cell lymphomas, diagnosed between January 2011 and December 2015, in the Hematology Department of the Sibiu County Emergency Hospital, Romania.
resultsWe included 126 (50.6%) male and 123 (49.4%) female patients with the average age being 68.2 years. Among all patients, 106 (42.6%) were diagnosed with chronic lymphocytic leukemia (CLL), 61 (24.5%) with marginal zone lymphoma (MZL), 53 (21.3%) with multiple myeloma (MM), 16 (6.4%) with follicular lymphoma (FL), nine (3.6%) with plasmacytoma, and four cases with hairy cell leukemia (HCL). The serum Hb value in the subject group varied between 2.6 g/dL and 17 g/dL. At diagnosis, 18 (7.2%) patients had severe anemia, 32 (12.9%) had moderate anemia, 58 (23.3%) had mild anemia, and 141 (56.6%) had no anemia at all at the time of diagnosis. In our group, the higher degree of anemia was correlated with a more advanced stage of the disease but not with the older age of the patients. Our study's highest median value of LDH corresponded to moderate anemia and the lowest value to patients who did not have anemia. Patients who did not have anemia at diagnosis had the best survival at five years, followed by those with mild anemia, then those with moderate anemia.
conclusionIn our cohort, subjects with the lowest Hb value at diagnosis had the worst survival. The results of our study conclude that anemia represents a negative impact factor not only on the patient's quality of life but also on their survival.
