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
MAIN
conclusionLateral Organ Boundaries Domain 13 (LBD13), which is expressed in emerged lateral roots and encodes a transcriptional activator, plays an important role in lateral root formation in Arabidopsis. Lateral roots (LRs) are major determinants of root system architecture, contributing to the survival strategies of plants. Members of the LBD gene family encode plant-specific transcription factors that play key roles in plant organ development. Several LBD genes, such as LBD14, 16, 18, 29, and 33, have been shown to play important roles in regulating LR development in Arabidopsis. In the present study, we show that LBD13 is expressed in emerged LRs and LR meristems of elongated LRs and regulates LR formation in Arabidopsis. Transient gene expression assays with Arabidopsis protoplasts showed that LBD13 is localized to the nucleus and harbors transcription-activating potential. Knock-down of LBD13 expression by RNA interference resulted in reduced LR formation, whereas overexpression of LBD13 enhanced LR formation in transgenic Arabidopsis. Analysis of β-glucuronidase (GUS) expression under the control of the LBD13 promoter showed that GUS staining was detected in LRs emerged from the primary root, but not in LR primordia. Moreover, both the distribution of LR primordium number and developmental kinetics of LR primordia were not affected either by knock-down or by overexpression of LBD13. Taken together, these results suggest that LBD13 is a nuclear-localized transcriptional activator and controls LR formation during or after LR emergence.
