CERA conversion to darbepoetin alfa in 154 hemodialysis patients.

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
purposeAnemia is a common complication in dialysis patients, usually treated with erythropoietin (EPO). Among available EPOs and analogs, continuous erythropoietin receptor activator (CERA) and darbepoetin alfa (DA) are the only two agents with a long duration of action, although they have almost never been formally compared in terms of efficacy. We took advantage of an accidental disruption in CERA supply to study the effect of its replacement with DA in the same patients.
methodsThe clinical and biological characteristics of 154 hemodialysis patients were retrospectively reviewed during the last 3 months on CERA compared to the first 4 months after replacement by DA, both ASE being administered by IV route. The comparison included EPO doses, hemoglobin levels, factors interfering with anemia (iron status assessment, iron doses, inflammation, quality of treatment) and was performed under the Bayesian paradigm.
resultsWe found no significant differences between the two EPOs in terms of doses or hemoglobin concentrations. Factors that could potentially influence hemoglobin concentrations also did not differ under CERA or DA. The stability of hemoglobin was identical with both EPOs. We provide a conversion factor which allows comparison of cost according to local prices.
conclusionsWe conclude that, in this observational "real life" study, the two EPOs are to be considered as equivalent.
