Geometric morphometrics of microscopic animals as exemplified by model nematodes.
Article in Nature protocols, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers.
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.
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
While a host of molecular techniques are utilized by evolutionary developmental (evo-devo) biologists, tools for quantitative evaluation of morphology are still largely underappreciated, especially in studies on microscopic animals. Here, we provide a standardized protocol for geometric morphometric analyses of 2D landmark data sets using a combination of the geomorph and Morpho R packages. Furthermore, we integrate clustering approaches to identify group structures within such datasets. We demonstrate our protocol by performing exemplary analyses on stomatal shapes in the model nematodes Caenorhabditis and Pristionchus. Image acquisition for 80 worms takes 3-4 d, while the entire data analysis requires 10-30 min. In theory, this approach is adaptable to all microscopic model organisms to facilitate a thorough quantification of shape differences within and across species, adding to the methodological toolkit of evo-devo studies on morphological evolution and novelty.
