mvh: An R tool to assemble and organize virtual herbaria from openly available specimen images.
Article in Applications in plant sciences. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Premise: Recent advances in imaging herbarium specimens have enhanced their use in biodiversity studies. However, user-friendly tools that facilitate the assembly of customized sets of herbarium specimen images on personal devices are still lacking. Methods and Results: Here we present the R package mvh ("my virtual herbarium"), which includes functions designed to search and download metadata and openly available images associated with herbarium specimens based on taxon or geography. We tested the functionalities of mvh by searching metadata associated with five sets of 10 vascular plant species and five sets of 10 terrestrial coordinates. The download function had a success rate of 99%, downloading 291 out of the 293 images found in the search. Possible reasons for download failure are discussed. Conclusions: As long as an internet connection is available, mvh simplifies the assembly and organization of virtual herbaria, thereby facilitating the investigation of novel empirical questions as well as trends in digitization efforts.
