Effectiveness and safety of pegylated filgrastim (Pelgraz®) for the prevention of febrile neutropenia during cancer chemotherapy in all-day practice in Germany.

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
purposeFebrile neutropenia (FN) is a common side effect of chemotherapy. It may be prevented by granulocyte colony-stimulating factors (G-CSF), requiring customization based on patients' risk factors, the type of cancer and chemotherapy, and the formulation used. This observational study investigated all-day use of a pegfilgrastim formulation, also available for self-administration.
methodsIn outpatient clinics across Germany, doctors recorded data of adult patients suffering from a malignant disease routinely treated with chemotherapy and pegfilgrastim.
resultsOverall, 1636 patients received pegfilgrastim, predominantly women suffering from yet untreated breast cancer, 62% being at moderate and 38% at high risk of FN. In total, 2.5% of patients experienced FN despite treatment with pegfilgrastim, with 52.5% requiring hospitalization; in 40%, subsequent chemotherapy had to be postponed or reduced in dose. FN incidence and hospitalization rates were slightly lower when pegfilgrastim was given for primary versus secondary prophylaxis whereas there was no difference when given on day 1 or any later day following chemotherapy. FN incidence was much higher in patients with hematological as compared to solid tumors, particularly when treated with BEACOPP regimens. By contrast, related hospitalization depended less on cancer type and chemotherapy. Pegfilgrastim counterbalanced patients' risk factors, but a previous FN episode and male sex still increased the risk of hospitalization. Overall, 13.4% of patients experienced infections. The most common side effect of pegfilgrastim was bone-related pain. The syringe and self-injector formulations showed comparable effectiveness and safety.
conclusionsPegfilgrastim (Pelgraz®) treatment appeared to be effective and safe in all-day practice.
