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 nuclear extract was prepared for the larval fat body of the silkworm, Bombyx mori, and a homologous in vitro system was developed for the transcription of major plasma protein gene of B.mori. The gene for SP1, a storage protein of B.mori, and adenovirus 2 major late (AdML) gene were faithfully transcribed under relatively high template concentrations in the nuclear extract prepared from the fat body of female fifth instar larvae. Complete inhibition of gene transcription by a low concentration of alpha-amanitin indicated that the reaction is catalyzed by RNA polymerase II. At low template concentration (0.6 nM) the fat body nuclear extract transcribed the homologous SP1 gene with high efficiency, while AdML gene and larval cuticle protein gene were only barely transcribed in the same extract. The SP1 gene deleted upstream of the TATA box sequence showed little effect on transcription, whereas mutations that destroy TATA sequence totally abolished the gene transcription. These results suggested that the core promoter region of SP1 gene spanning between positions -44 and +16 is essential for the fat body specific transcription in vitro.
