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

Dietary restriction extends lifespan in many organisms, but little is known about how it affects hematophagous arthropods. We demonstrated that diet restriction during either larval or adult stages extends Aedes aegypti lifespan. A. aegypti females fed either single or no blood meals survived 30-40% longer than those given weekly blood meals. However, mosquitoes given weekly blood meals produced far more eggs. To minimize reproduction's impact on lifespan, adult mosquitoes were fed artificial blood meals containing <10% of the protein in normal human blood, minimizing egg production. A. aegypti fed artificial blood meals containing 25mg/ml of BSA had significantly shorter lifespans than those fed either 10 or 5mg/ml. To assess the impact of larval dietary restriction on adult lifespan, we maintained larval A. aegypti on 2X, 1X (normal diet), 0.5X or 0.25X diets. Adult mosquitoes fed 0.5X and 0.25X larval diets survived significantly longer than those fed the 2X larval diet regardless of adult diet. In summary, dietary restriction during both larval and adult stages extends lifespan. This diet-mediated lifespan extension has important consequences for understanding how dietary restriction regulates lifespan and disease transmission.
