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
Organ size is a major agronomic trait that determines grain yield and biomass production in crops. However, the molecular mechanisms controlling organ size, especially in legumes, are poorly understood. Using forward genetic approaches in a Tnt1 insertion mutant population of the model legume Medicago truncatula, we identified SMALL LEAF AND BUSHY1 (SLB1), which is required for the control of organ size and lateral branching. Loss of function of SLB1 led to reduced leaf and flower size but increased lateral branch formation in M. truncatula. SLB1 encodes an F-box protein, an orthologue of Arabidopsis thaliana STERILE APETALA (SAP), that forms part of an SKP1/Cullin/F-box E3 ubiquitin ligase complex. Biochemical and genetic analyses revealed that SLB1 controls M. truncatula organ growth and lateral branching by modulating the stability of BIG SEEDS1 (BS1). Moreover, the overexpression of SLB1 increased seed and leaf size in both M. truncatula and soybean (Glycine max), indicating functional conservation. Our findings revealed a novel mechanism by which SLB1 targets BS1 for degradation to regulate M. truncatula organ size and shoot branching, providing a new genetic tool for increasing seed yield and biomass production in crop and forage legumes.
