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
The tomato lat52 gene encodes an essential cysteine-rich protein preferentially transcribed in the vegetative cell during pollen maturation. Detailed analyses of the identity, organization and role of cis-regulatory elements in controlling the precise developmental and tissue-specific expression of lat52 during pollen development were performed. Analysis of a series of 5' promoter deletion mutants stably introduced into tobacco demonstrated differential developmental activation of deletion mutants during pollen development. All major cis-regulatory elements required for pollen-specific transcription were located within the upstream region -492 to -52. This region was shown to comprise three independent activator domains A, B and C, each sufficient to activate the minimal CaMV 35S promoter in a pollen-specific manner. 5' deletion and gain of function approaches were used to show that domain A and the previously defined motif PBII (sub-domain B1) were largely redundant in the presence of downstream sequences in mature pollen. Within domain B two novel pollen-specific sub-domains B2 and B3 were identified. Within domain C, the activity of the PBI motif (sub-domain C1) was shown to be strictly dependent upon a downstream 20 bp pollen-specific activator unit -72 to -52 (sub-domain C2), containing two novel co-dependent regulatory elements AGAAA and TCCACCATA. These results demonstrate that transcriptional activation of lat52 is controlled by a complex of pollen-specific cis-regulatory elements which cooperate to achieve maximum levels of gene expression throughout pollen maturation. Alternative models of the interaction of identified cis-regulatory elements with putative trans-acting factors within the lat52 promoter and their developmental utilization are presented.
