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
DEHYDRATION-RESPONSIVE ELEMENT BINDING PROTEIN2A (DREB2A) is a key transcription factor for drought and heat stress tolerance in Arabidopsis thaliana. DREB2A induces the expression of dehydration- and heat stress-inducible genes under the corresponding stress conditions. Target gene selectivity is assumed to require stress-specific posttranslational regulation, but the mechanisms of this process are not yet understood. Here, we identified DNA POLYMERASE II SUBUNIT B3-1 (DPB3-1), which was previously annotated as NUCLEAR FACTOR Y, SUBUNIT C10 (NF-YC10), as a DREB2A interactor, through a yeast two-hybrid screen. The overexpression of DPB3-1 in Arabidopsis enhanced the expression of a subset of heat stress-inducible DREB2A target genes but did not affect dehydration-inducible genes. Similarly, the depletion of DPB3-1 expression resulted in reduced expression of heat stress-inducible genes. Interaction and expression pattern analyses suggested the existence of a trimer comprising NF-YA2, NF-YB3, and DPB3-1 that could synergistically activate a promoter of the heat stress-inducible gene with DREB2A in protoplasts. These results suggest that DPB3-1 could form a transcriptional complex with NF-YA and NF-YB subunits and that the identified trimer enhances heat stress-inducible gene expression during heat stress responses in cooperation with DREB2A. We propose that the identified trimer contributes to the target gene selectivity of DREB2A under heat stress conditions.
