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

Synthesis of certain members of the tropomyosin family of microfilament-associated proteins is suppressed in fibroblasts neoplastically transformed by a number of retroviral oncogenes, by transforming growth factor alpha, and by chemical mutagens. To test whether tropomyosin suppression is a required event in neoplastic transformation, expression of one of two suppressed tropomyosins in NIH 3T3 mouse cells transformed by the ras oncogene was restored by retrovirally mediated cDNA transfer. Cells expressing the inserted cDNA showed partial restoration of microfilament bundle formation (which is typically deranged in transformed cells) together with increased cytoplasmic spreading. More importantly, they lost anchorage-independent growth capability, and the onset of tumor growth in athymic mice was delayed. When tumors arose they no longer expressed the inserted cDNA. These observations support the conclusion that tropomyosin suppression is a necessary event for the expression of components of the transformed phenotype, particularly with respect to anchorage-independent growth and tumorigenesis, which correlate closely with neoplastic potential. This potentially reversible requirement may link different initial events produced by a variety of oncogenic modalities to a common pathway leading to neoplastic growth.
