A randomized crossover study of single biweekly administration of epoetin-α compared with darbepoetin-α in chronic kidney disease patients not receiving dialysis.

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
backgroundRecent evidence demonstrates that high doses of epoetin-alpha (EPO-α) can be administrated at extended intervals, despite its relatively short serum half-life. However, no prospective randomized trials on the effects of extended dosing intervals of EPO-α compared with darbepoetin-alpha (DA-α) have been performed. This study was designed to investigate whether a single biweekly (Q2W) administration of a high dose of EPO-α is as effective as DA-α for anemia in chronic kidney disease (CKD) patients not receiving dialysis.
methodsSixty non-dialysis CKD patients were equally randomized to either Q2W subcutaneous EPO-α (10,000 unit) or DA-α (50 μg) therapy groups for the first 6 weeks. After a 6-week washout period, the participants of the EPO-α and DA-α treatment groups switched to the alternate regimen for 6 weeks. The mean hemoglobin (Hb) levels after erythropoiesis stimulating agent (ESA) therapy and percentage change in Hb levels from baseline to the end of the study were analyzed.
resultsThe mean Hb levels of postESA therapy increased significantly compared with those of preESA therapy in both ESA regimens. The percentage increase in Hb levels and erythropoietin resistance index did not show a significant difference between the different ESA regimens. No difference was observed between the regimens regarding mean Hb levels after ESA therapy. Additionally, there were no serious adverse effects leading to withdrawal from treatment.
conclusionBiweekly high doses of EPO-α therapy may be equally as effective as Q2W DA-α therapy in maintaining target Hb levels in non-dialysis CKD patients.
