Substitution of cyclophosphamide in the modified BuCy regimen with fludarabine is associated with increased incidence of severe pneumonia: a prospective, randomized study.

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
The modified busulfan-cyclophosphamide (mBuCy) regimen, combined with hydroxyurea, cytarabine and semustine, is the most frequently used myeloablative conditioning regimen for allogeneic hematopoietic stem cell transplantation in our unit. It is unknown, however, whether fludarabine can be substituted for cyclophosphamide in the mBuCy regimen. We carried out a prospective study to compare modified busulfan-fludarabine (mBuF) with mBuCy, aiming to reduce the treatment-related mortality, with non-inferiority of other outcomes. The mBuCy regimen consisted of hydroxyurea 80 mg/kg on day -10; cytarabine 2 g/m(2) on day -9; busulfan 9.6 mg/kg, intravenously on day -8 through -6; and cyclophosphamide 3.6 g/m(2) on day -5 and -4 and semustine 250 mg/m(2) on day -3. In the mBuF regimen, cyclophosphamide was substituted with fludarabine 30 mg/m(2) through day -5 to -1. Mobilized blood and marrow stem cells were collected from HLA-matched siblings. The trial was suspended due to a tendency of higher incidence of severe pneumonia in the mBuF arm, in which 105 patients were enrolled. After follow-up for another 22 months, a significantly increased incidence of severe pneumonia (31.1 %) was observed in the mBuF arm (11.6 % in mBuCy). This finding suggests that it is uncertain whether it is appropriate to substitute fludarabine for cyclophosphamide under any drug combination.
