Synchronization of administrations of chemotherapy and erythropoiesis-stimulating agents and frequency of associated healthcare visits.

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 erythropoiesis-stimulating agents (ESAs), darbepoetin alfa (DA), and epoetin alfa (EA) differ with respect to dosing schedule in chemotherapy-induced anemia. DA can be administered less frequently than EA, which may increase synchronicity between chemotherapy and ESA schedules. This study compared DA and EA with respect to frequency of synchronization and frequencies of total and ESA healthcare visits in current clinical practice.
methodsA retrospective analysis of ESA utilization during ESA episodes of care was conducted on all cancer patients identified in the SDI health oncology electronic medical records database who underwent chemotherapy and received ESA therapy from July 1, 2007 to March 31, 2010 (n = 6522 DA, n = 3,439 EA).
resultsThe frequency of synchronization (chemotherapy and ESA therapy on the same day) was higher with DA (67 %) than EA (58 %) (p < 0.001). The odds that an ESA administration was synchronized with chemotherapy were higher with DA compared with EA (odds ratio = 1.46, 95 % CI: 1.37, 1.54). Compared with EA, DA patients had 2.3 fewer visits with an ESA administration (p < 0.001) and 3.0 fewer total visits (p < 0.001).
conclusionsCompared with patients receiving EA, DA patients were more likely to have an ESA administration on the same healthcare visit as chemotherapy and had fewer visits for any cause or for ESA administration. These results suggest that through greater synchronization of ESA and chemotherapy administrations, DA may reduce patient and practice burden and healthcare utilization.
