SLEEPLESS, a gene conferring nyctinastic movement in legume.
Article in Journal of plant research, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
A genetic approach was attempted to identify the gene responsible for nyctinastic movement in legume. Seeds of the model legume Lotus japonicus were treated with ethylmethane sulfonate and screening of 40,000 M2 seeds led to the isolation of one mutant named sleepless. sleepless is incapable of closing its leaflets towards the adaxial side at night. The pulvini at the leaflet base were found to be replaced with petiole-like structure in sleepless. Wild-type pulvini comprise many compressed cells, whereas the corresponding region in sleepless is made up of roundish cells in the cortical parenchyma and highly elongated cells in the epidermis, particularly in the leaf-length direction. Based on the results of histological examination, I propose a possible model of a developmental pathway leading to nyctinastic movement.
