1 · What the graph read from it

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.

2 · The registry

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

Lentivirus can be engineered to be a highly potent vector for gene therapy applications. However, generation of clinical grade vectors in enough quantities for therapeutic use is still troublesome and limits the preclinical and clinical experiments. As a first step to solve this unmet need we recently introduced a baculovirus-based production system for lentiviral vector (LV) production using adherent cells. Herein, we have adapted and optimized the production of these vectors to a suspension cell culture system using recombinant baculoviruses delivering all elements required for a safe latest generation LV preparation. High-titer LV stocks were achieved in 293T cells grown in suspension. Produced viruses were accurately characterized and the functionality was also tested in vivo. Produced viruses were compared with viruses produced by calcium phosphate transfection method in adherent cells and polyethylenimine transfection method in suspension cells. Furthermore, a scalable and cost-effective capture purification step was developed based on a diethylaminoethyl monolithic column capable of removing most of the baculoviruses from the LV pool with 65% recovery.
