Hemoglobin decline in cancer patients receiving chemotherapy without an erythropoiesis-stimulating agent.
Article in Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
purposeThe aim of this study was to examine the rate and timing of hemoglobin decline from <10 g/dL to <9 g/dL in cancer patients receiving chemotherapy.
methodsPooled data from the placebo arms of six randomized, controlled trials (RCTs) of darbepoetin alfa and data from an aggregated US community oncology clinic electronic medical records (EMR) database were analyzed. Patients had baseline hemoglobin ≥10 g/dL (RCTs) or baseline hemoglobin between ≥10 g/dL and <11 g/dL (EMR episodes) that declined to <10 g/dL at least once during the study period. The proportion of patients/episodes with hemoglobin decline to <9 g/dL by 3, 6, and 9 weeks without erythropoiesis-stimulating agents was estimated from data in each of the data sources, as was the rate of transfusions in the RCTs.
resultsData from 411 patients receiving placebo in the RCTs and 10,523 patients (10,942 episodes) in the EMR database were analyzed. Forty percent and 35 % of RCT patients and EMR episodes, respectively, had a hemoglobin decline from <10 g/dL to <9 g/dL at week 3, 54 % and 43 % at week 6, and 58 % and 46 % at week 9. Of patients in the RCTs, 43 % required an RBC transfusion.
conclusionsHemoglobin can rapidly decline in cancer patients receiving chemotherapy with hemoglobin levels around 10 g/dL, particularly in patients ≥65 years of age. The rapid rate of hemoglobin decline in these patients should be considered for optimal anemia management.
