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 positive association between agonist-stimulated cyclic AMP production in vitro and both experimentally induced (B16 melanoma) and spontaneous (fibrosarcoma) metastases were found. Five B16 melanoma cell lines producing varying degrees of lung colonization following intravenous injection and three hamster fibrosarcoma cell lines producing a varying number of metastases in lungs and regional lymph nodes after removal of the primary tumour were studied. Agonist-stimulated (forskolin and melanocyte-stimulating hormone), but not basal cyclic AMP accumulation, increased with increasing metastatic potential. This relationship did not extend to other intracellular signalling systems as determined by investigation of basal or foetal-calf stimulated phosphatidylinositol hydrolysis for either tumour type. Intracellular free calcium was also similar in B16 melanoma cell lines of varying metastatic potential.
