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

Biological individuality was a hotly debated concept in nineteenth-century German biology, both in botany and in zoology. Much discussion centered on a comparison of higher plants with colonial organisms that are subject to polymorphism and exhibit division of labor among their parts. Building on the work of Matthias Jakob Schleiden, Johannes Müller, Rudolf Leuckart, and especially the botanist Alexander Braun, Haeckel in his writings continued to refine his theory of relative individuality. Haeckel recognized three kinds of individuality: physiological, morphological, and genealogical, the latter two hierarchically structured. These distinctions allowed him to embed in his theory of relative (biological) individuality the threefold parallelism of ontogeny, phylogeny, and classification. For Haeckel, this threefold parallelism provided the strongest proof for Darwin's theory of descent with modification.
