Linking reproduction, locomotion, and habitat use in the Trinidadian guppy (Poecilia reticulata).
Article in Oecologia, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Pregnancy inhibits locomotion, increases predation risk and may translate into reduced survival. The extent to which animals modify behavior in the wild to compensate for the locomotor costs of pregnancy remains poorly understood. We have investigated how reproductive allocation (RA-the proportion of body mass devoted to reproduction) affects locomotor performance and habitat use in Trinidadian guppy (Poecilia reticulata) populations from low- and high-predation regimes. During steady swimming, females with high RA had increased tail beat amplitudes, indicating increased swimming costs. Females with high RA also exhibited slower escape velocities, which may result in an increased risk of predation. In low-predation localities, females with high RA used habitats with a lower water velocity, suggesting that females may be modifying behavior to offset the locomotor costs of pregnancy. Habitat use in high-predation localities was severely restricted to areas without predators, which had a relatively slower water velocity with little or no variation in current. These results provide a link between the performance-related costs of reproduction and behavior in a natural setting and show that animals may compensate for reproductive traits that constrain locomotor performance by modifying habitat use.
