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

During Drosophila aging mortality rate increases exponentially and progeny production per animal declines dramatically, correlating with decreased number and division of somatic and germ-line stem cells in the gonads. To search for genes that might promote both longevity and fecundity, a P element transposon (PdL), containing an outwardly directed, doxycycline-inducible promoter was used to generate conditional mutations. Mutant females were screened for increased fecundity at late ages in the presence of doxycycline. Two genes were identified, named hebe (CG1623) and magu (CG2264), that when over-expressed in adult flies could increase life span by approximately 5-30% in both sexes and increase female fecundity at late ages. Transcripts for magu are enriched in the Drosophila stem cell niche region, and magu encodes a protein related to the human SMOC2 regulator of angiogenesis. While moderate over-expression of magu in adult females increased fecundity at late ages, high-level over-expression of magu was maternal-effect lethal. The data demonstrate that adult-specific over-expression of hebe and magu can increase life span and modulate female fecundity, and provide further evidence against obligatory trade-offs between reproduction and longevity.
