Trade-offs between reproduction and health in free-ranging African striped mice.

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.
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
Energy is limited and must be allocated among competing life-history traits. Reproduction is considered one of the most energetically demanding life-history stages. Therefore, the amount of energy an individual invests in reproduction might carry fitness costs through reduced energy allocation to other activities such as health maintenance. We investigated whether reproduction impacts health in the seasonally breeding African striped mouse (Rhabdomys pumilio). We measured health in individuals that reproduced (breeders) and individuals that did not reproduce (their adult offspring) and tested whether: (1) breeders' health before reproduction was similar to that of their offspring (representing a baseline); (2) breeders' health deteriorated after reproduction; (3) breeders' health after reproduction was worse than that of their offspring. We collected blood samples from 12 breeding females and 11 breeding males both at the onset and at the end of the breeding season and from 12 adult daughters and 11 adult sons that did not reproduce at the end of the breeding season. Health was assessed using serum biochemistry analysis with VetScan Abaxis. Breeders differed considerably in their health before and after reproduction, particularly in parameters associated with digestion (lower amylase in males), metabolism (lower albumin, alkaline phosphatase, creatinine and glucose), osmoregulation (lower potassium and phosphorous in females) and immunity (higher globulin and altered alanine aminotransferase). Our results suggest that with the onset of breeding striped mice shifted their energy allocation from maintaining health to reproduction, indicating that investment into reproduction carries significant health costs.
