10-year stability of clinical-grade serum-free γ-retroviral vector-containing medium.
Article in Gene therapy, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
More than 10 years ago, we developed an efficient protocol for serum-free retroviral transduction of human hematopoietic stem cells derived from mobilized peripheral blood. After upscaling of the methodology, serum-free retroviral gibbon-ape leukemia virus (GALV) pseudotype PG13/LN vector supernatant produced under strict good manufacturing practice (GMP) conditions was used in the first clinical gene-marking trial in Germany. In this study, we analyzed the titer and transduction efficiency of this serum-free clinical-grade retroviral supernatant 10 years after production to evaluate the long-term stability. Long-term storage and transport on dry ice resulted in modestly decreased titers and levels of transduction efficiency in CD34+ cells ranging from 38.4 to 49.1%. We conclude that the stability of retroviral vectors in serum-free medium allows extended storage and distribution of approved clinical-grade retroviral vector stocks to distant sites in multicenter clinical trials.
