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
Previously, we confirmed that BaEV-LVs outperformed VSV-G-LVs for gene delivery or correction of human T cells, B cells, NK cells and HSPCs correlating with high expression of its receptors, ASCT-1 and ASCT-2 on these cells. Since HERV-W gp uses the same entry receptors, we compared transduction efficiencies for BaEV-LVs and HERV-W-LVs in hematopoietic cells. HERV-W LV transduction was efficient but inferior to BaEV-LV in TCR-stimulated T cells (40% versus 80%) and this low efficiency was even more pronounced in IL-7/IL-15 pre-stimulated T cells. BaEV-LVs were significantly superior over HERV-W-LVs for the transduction of B cells and NK cells. High HERV-W-LV mediated transduction levels were achieved for pre-stimulated hCD34+ cells, which remained though lower than for the BaEV-LVs. Additionally, BaEV-LVs reached over 80% of transduction in severe combined immunodeficiency (SCID) repopulating cells (SRC) in 6/6 engrafted NBSGW mice. HERV-W-LVs reached this transduction level in 1/5 mice, while 3/5 engrafted NBSGW mice reached significantly lower transduction levels (20-50%). For both vectors the transduction levels were equivalent in the lymphoid and myeloid lineages in all hematopoietic tissues, suggesting transduction of immature HSPCs. Summarizing, BaEV-LVs outperformed HERV-W-LVs for transduction of important gene therapy target cells such as NK, B, T cells and CD34+ HSPCs.
