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

Cluster 1 streptokinases (SK1) from Streptococcus pyogenes (GAS) show substantially higher human plasminogen (hPg) activation activities and tighter hPg binding affinities than cluster 2b streptokinases (SK2b) in solution. The extent to which the different domains of SK are responsible for these differences is unknown. We exchanged each of the three known SK domains (α, β, and γ) between SK1 and SK2b and assessed the function of the resulting variants. Our results show that primary structural differences in the β-domains dictate these functional differences. This first report on the primary structure-functional relationship between naturally occurring SK1 and SK2b sheds new light on the mechanism of hPg activation by SK, a critical virulence determinant in this species of human pathogenic bacteria.
