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

Annual migration of ungulates is often correlated with regional and seasonal plant growth, but are smaller scale movements of individuals related to fitness? We investigated the response of wild caribou to variation in plant phenology. We used faecal transects to evaluate spatial differences in diet in one growing season after the onset of spring plant growth had occurred (green-up). We captured 110 females (1-15 years) from the Teshekpuk Caribou herd over three years (14-28 June 2022-2024). We measured diet and corresponding indices of body condition of captured caribou at various stages of green-up. Plant growth (normalized differentiation vegetation index) at capture locations was greatest in 2023 when captures followed the onset of green-up. We sampled faeces and blood to measure concentrations of albumin and urea N in serum, and to measure δ
