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

Mating induces profound changes in female insect behavior and physiology. In Drosophila melanogaster, mating causes a reduction in sexual receptivity and an elevation in egg production for at least 5 days. Injection of the seminal fluid sex peptide (SP) induces both responses in virgin females, but only for 1-2 days. The role of SP in eliciting the responses to mating remains to be elucidated. Functional redundancy between seminal fluid components may occur. In addition, mating with spermless males results in brief (1- to 2-day) post-mating responses, indicating either that there is a "sperm effect" or that sperm act as carriers for SP or other seminal fluid components. Here we used RNA interference to suppress SP expression, to determine whether SP is required to elicit full post-mating responses, the magnitude of responses due to other seminal fluid components, and whether SP accounts for the "sperm effect." Receptivity was higher and egg production lower in females mated to SP knock-down males than in controls. Comparison with virgins showed that the responses were brief. SP is therefore required for normal magnitude and persistence of postmating responses. Sperm transfer and use were normal in mates of SP knock-down males, yet their post-mating responses were briefer than after normal matings, and similar to those reported in mates of spermless son-of-tudor males. The prolonged "sperm effect" on female receptivity and egg production is therefore entirely attributable to SP, but sperm are necessary for its occurrence.
