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
Some species of the holoparasitic flowering plant genus Cuscuta, like C. reflexa, have retained a plastid genome that encodes photosynthesis-related gene products as well as the plastid-encoded RNA polymerase (PEP). In contrast, other species like C. gronovii and C. subinclusa have lost the rpo genes coding for the PEP subunits while photosynthetic genes have been retained. In order to ensure expression of the photosynthesis-related genes in the absence of PEP, a number of adaptations within the plastid genome were required that enable gene transcription mediated exclusively by the nuclear-encoded plastid RNA polymerase (NEP). In this study we analyzed promoter sequence conservation and transcription start sites of a typical PEP gene of non-parasitic plants, rbcL, which codes for the large subunit of ribulose bisphosphate carboxylase/oxygenase. We show that despite high sequence conservation of the coding region of rbcL among different Cuscuta species and tobacco, the 5' non-coding regions of C. gronovii and C. subinclusa have suffered extensive deletions encompassing the PEP promoter that is present in C. reflexa and tobacco. Primer-extension analyses enabled the identification of transcripts initiated at NEP promoter motifs in C. gronovii and C. subinclusa that are not detectable in the 5' non-coding region of C. reflexa.
