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 hunting hypothesis holds that ancestral human males favored their own mates and children in sharing meat gained from big game hunting, a practice said to have led to the origin of nuclear families and related changes in life history. Data from East African Hadza hunter-gatherers operating in an environment like that prevalent when and where Homo evolved contradict key elements of this idea. An alternative model, the grandmother hypothesis, holds that senior women's foraging and food sharing led to life history changes that favored mate guarding, not paternal provisioning, in the formation of nuclear family-like social units. Relevant data and theory are reviewed and evaluated.
