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
Plants in the genus Cucumis (cucumber and melon) have the largest mitochondrial genomes known among all plants, due in part to the accumulation of repetitive DNAs of varying complexities. Recombination among these repetitive DNAs should produce highly rearranged mitochondrial genomes relative to the smaller mitochondrial genomes of related plants. We cloned and sequenced mitochondrial genomic regions near the rRNA, atp9 and cob genes from cucumber, melon, squash and watermelon (all members of the Cucurbitaceae family), and compared to the previously sequenced mitochondrial genomes of Arabidopsis thaliana and sugar beet to study the distribution and arrangement of coding and repetitive DNAs. Cucumber and melon had regions of concentrated repetitive DNAs spread throughout the sequenced regions; few repetitive DNAs were revealed in the mitochondrial genomes of A. thaliana, sugar beet, squash and watermelon. Recombination among these repetitive DNAs most likely produced unique arrangements of the rrn18 and rrn5 genes in the genus Cucumis. Cucumber mitochondrial DNA had more pockets of dispersed direct and inverted repeats than melon and the other plants, and we did not reveal repetitive sequences significantly contributing to mitochondrial genome expansion in both cucumber and melon.
