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

The HDL (heat dissipation limitation) hypothesis posits that mammalian energy budgets (SuSMR, sustained metabolic rate) are limited by the ability to dissipate metabolic heat. The HDL hypothesis has been tested in lactating mice but rarely systematically differs in SuSMR. Here, we used lines of laboratory mice divergently selected for basal metabolic rate (BMR) and effectively co-selected for SuSMR. We exposed lactating females to 23 and 30°C and manipulated their heat dissipation abilities by fur shaving. Exposure to 30°C did not affect the high BMR mice's litter mass but increased litter mass in the low BMR mice. Fur shaving did not affect litter mass. However, it decreased body temperature (
