Preparation of Mitotic Chromosomes with the Dropping Technique.
Article in Methods in molecular biology (Clifton, N.J.), 2023. 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
The quality of chromosome preparation influences all downstream analyses and is therefore crucial. Hence, numerous protocols exist to produce microscopic slides with mitotic chromosomes. Nevertheless, due to the high content of fibers in and around a plant cell, preparation of plant chromosomes is still far from trivial and needs to be fine-tuned for each species and tissue type. Here, we outline the "dropping method," a straightforward and efficient protocol to prepare multiple slides with uniform quality from a single chromosome preparation. In this method, nuclei are extracted and cleaned to produce a nuclei suspension. In a drop-by-drop manner, this suspension is then applied from a certain height onto the slides, causing the nuclei to rupture and the chromosomes to spread. Due to the physical forces that accompany the dropping and spreading process, this method is best suited for species with small- to medium-sized chromosomes.
