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

Amphibians face global declines linked to anthropogenic environmental change, including modifications to freshwater habitats. Human impacts on water chemistry, including acid rain and run-off of road salt into wetlands, may affect the physiology of amphibians with aquatic life stages. Specifically, water pH varies among freshwater habitats and affects amphibian development, behaviour, and physiology. For example, changes in skin pH affect the activity of enzymes on the skin, including those involved in antimicrobial functions. In this study, we explored the ability of free-ranging amphibians to maintain homeostasis across a range of naturally occurring water pH and salinity. We sampled two species of frogs at 19 wetlands around Peterborough, Ontario, measuring water pH, water salinity, and the skin pH of northern leopard frogs (
