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

Recombinant protein and virus-like particle (VLP) production based on the baculovirus expression vector system is fast, flexible, and offers high yields. Independent from the product, a multitude of parameters are screened during process development/optimisation. Early development acceleration is a key requirement for economic efficiency, and µ-scale bioreactor systems represent an attractive solution for high-throughput (HTP) experimentation. However, limited practical knowledge is available on the relevance and transferability of screening data to pilot scales and manufacturing. The main goal of the present study was to evaluate a HTP µ-bioreactor platform with respect to its aptitude as a screening platform mainly based on transferability of results to benchtop bioreactors representing the conventional production regime. Second question was to investigate to what extent the online sensors of the µ-bioreactor contribute to process understanding and development. We demonstrated that transferability of infection screening results from the HTP µ-bioreactor scale to the benchtop bioreactor was equal or better than that from shaker cultivation. However, both experimental setups turned out to be sub-optimal solutions that only allowed for a first and rough ranking with low relevance in the case of absolute numbers. Bioreactor yields were up to one order of magnitude higher than the results of screening experiments.
