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

We have previously described the isolation and sequencing of cDNA clones encoding rat interleukin-2 (IL-2) and interleukin-4 (IL-4). In the present study, we report the generation of stably transfected Chinese hamster ovary (CHO) cell lines which constitutively synthesize and secrete high levels of rat recombinant IL-2 (rIL-2) and IL-4 (rIL-4). The expression of the cytokine cDNA sequences is driven by the human cytomegalovirus promoter/enhancer within the respective pEE6. HCMV-GS vector constructs, following the successful transfection and isolation of methionine sulphoximine (MSX)-resistant CHO cell lines. Analyses of metabolically labelled CHO.rIL-2 and CHO.rIL-4 have been performed, in addition to studies which demonstrate certain biological properties of these recombinant cytokines including T-cell growth factor activity (rIL-2) and the ability to enhance expression of class II major histocompatibility complex (MHC) molecules on spleen cells (rIL-4). The availability of large quantities of these rat recombinant cytokines, conveniently produced by a mammalian cell line, will prove invaluable in future studies into the induction and regulation of immune responses in this species.
