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
Long terminal repeat retrotransposons (LTR-RTs) make up a considerable portion of plant genomes. New insertions of these active LTR-RTs modify gene structures and functions and play an important role in genome evolution. Therefore, identifying active forms of LTR-RTs could uncover the effects of these elements in plants. Extrachromosomal linear DNA (eclDNA) forms during LTR-RT replication; therefore, amplification LTRs of eclDNAs followed by sequencing (ALE-seq) uncover the current transpositional potential of the LTR-RTs. The ALE-seq protocol was validated by identification of Tos17 in callus of Nipponbare cultivar. Here, we identified two active LTR-RTs belonging to the Oryco family on chromosomes 6 and 9 in rice cultivar Dongjin callus based on the ALE-seq technology. Each Oryco family member has paired LTRs with identical sequences and internal domain regions. Comparison of the two LTR-RTs revealed 97% sequence identity in their internal domains and 65% sequence identity in their LTRs. These two putatively active Oryco LTR-RT family members could be used to expand our knowledge of retrotransposition mechanisms and the effects of LTR-RTs on the rice genome.
