Predictors of response to erythropoiesis-stimulating agents (ESA) in cancer patients: the role of baseline serum epoetin level.
Review in Clinical & translational oncology : official publication of the Federation of Spanish Oncology Societies and of the National Cancer Institute of Mexico, 2008. 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
Anemia is the most frequent hematologic abnormality among cancer patients. Its pathophysiology comprises reduction in erythrocyte half-life, poor iron reutilization by the bone marrow, and inadequate response to erythropoietin (EPO), with reduced endogenous EPO (eEPO) levels. Current treatment implies the use of erythropoiesis- stimulating agents (ESA), to which 35-48% of patients show primary resistance. The search for predictors of response to ESA treatment has been inconclusive. Iron or vitamin deficiency, the recent need for transfusion, or a lack of hemoglobin increase within the first 2-4 weeks usually predict resistance to ESA. High serum eEPO levels at treatment initiation (>100-150 mU/ml) may also predict resistance, especially in hematologic malignancies, but the results in solid tumors are not consistent. Although patients with cancer-related anemia show higher eEPO levels than patients without anemia, there is extreme variability among individuals. Future studies are needed to clarify eEPO usefulness in predicting response to ESA treatment.
