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

The effect of serum type and concentration on recombinant protein expression in vaccinia virus infected HeLa S3 cells was studied in both static and suspension culture. A model heterologous protein,β-galactosidase (β-gal), was used. Calf and horse sera in the range of 0.5-10%(v/v) were investigated. In static culture, the calf serum concentration did not show any significant influence on the β-gal production which was almost completed within 24h postinfection (pi). Higher horse serum concentration, on the other hand, resulted in higher β-gal concentration which continued to increase until 48 h pi. Total β-gal concentrations in 0.5% calf serum at 24 h pi and 10% horse serum at 48 h pi were 2.2±0.7 and 2.2±0.1 IU/ml, respectively. In suspension culture, both sera showed their respective effects on the β-gal production similar to those observed in static culture, indicating that the cultivation method had little influence on β-gal production. Accordingly, the use of 0.5% calf serum after virus infection in recommended for economical β-gal production.
