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

A novel, optical sensor was fixed in a new type of disposable bioreactor, Tubespin, for the on-line (real-time) monitoring of dissolved oxygen concentrations during cell culture. The cell density, viability and volumetric mass transfer coefficient were also determined to further characterize the bioreactors. The k(L)a value of the Tubespin at standard conditions was 24.3 h(-1), while that of a spinner flask was only 2.7 h(-1). The maximum cell density in the Tubespin bioreactor reached 6 × 10(6) cells mL(-1), which was two times higher than the cell density in a spinner flask. Furthermore, the dynamic dissolved oxygen level was maintained above 90% air-saturation in the Tubespin, while the value was only 1.9% in a spinner flask. These results demonstrate the competitive advantage of using the Tubespin system over spinner flasks for process optimization and scale-down studies of oxygen transfer and cell growth.
