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

Biomass concentration is a crucial parameter while monitoring Escherichia coli bioprocesses. Real-time monitoring of this attribute is preferable to discrete measurement, as it immediately detects deviations, reduces sampling efforts and thereby minimizes the risk of contamination. Therefore, the potential of dielectric spectroscopy for continuous monitoring of E. coli cultures was investigated. Two datasets were acquired across culture batches in a benchtop bioreactor: ∆ permittivity and the dielectric spectrum. For each batch, variations in ∆ permittivity followed the OD
