Suspension-Adapted HEK293FT Cells Enable High-Density Transfection for Efficient Lentiviral Vector Production in CAR-T Therapy.
Article in Bioengineering (Basel, Switzerland), 2026. 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
Lentiviral vector (LV) production for CAR-T therapy remains challenging due to the limited scalability of adherent HEK293 cell cultures. To address this, we adapted HEK293FT cells directly to serum-free FreeStyle 293 Expression Medium, generating a novel suspension cell line, HEK293FT-DS. We characterized growth kinetics, stability over 35 passages, and transient transfection parameters (PEI:DNA ratio, cell density). The suspension-adapted cells grew with >93% viability and a specific growth rate of 0.54 day
