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 amplified and sequenced the gene encoding Esterase-P (Est-P) in 10 strains of Drosophila melanogaster. Three premature termination codons occur in the coding region of the gene in two strains. This observation, together with other indirect evidence, leads us to propose that Est-P may be a pseudogene in D. melanogaster. Est-P would be a "cryptic" pseudogene, in the sense that it retains intact the coding sequence (without stop codons and other alterations usually observed in pseudogenes) in most D. melanogaster strains. We conjecture that the beta-esterase cluster may consist in other Drosophila species of functional and nonfunctional genes. We also conjecture that the rarity of detected pseudogenes in Drosophila may be due to the difficulty of discovering them, because most of them are cryptic.
