Hourly monitoring of circulating CD34+ cells to optimize timing of autologous apheresis in pediatric patients.
Trial report in Bone marrow transplantation, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In order to increase the CD34+ cell yield in children undergoing autologous stem cell transplantation, the optimum time of apheresis after G-CSF administration has still to be found. We prospectively studied the mobilization of CD34+ cells and white blood cells in the peripheral blood (PB) of 20 pediatric patients before leukapheresis. The monitoring schedule covered 12 h, with blood samples taken before and at 2, 4, 5, 6, 7, 8, 10 and 12 h after G-CSF administration when 10 CD34+ cells/mul were reached. CD34+ cells were measured by flow cytometric analysis both in the single- and dual-platform setting. Two different patterns of mobilization (POM) emerged: 12 patients showed an increase in CD34+ cells in PB during the first 4 h after G-CSF (POM I), while eight patients had an initial decrease of CD34+ cells. However, all patients together showed a significant increase of CD34+ cells about 10 h after G-CSF administration. Further studies with more patients, using an enhanced monitoring schedule will be required to refine the results.
