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 plant hormone auxin regulates growth and development by modulating the stability of auxin/indole acetic acid (Aux/IAA) proteins, which in turn repress auxin response factors (ARFs) transcriptional regulators. In transient assays performed in immature sunflower embryos, we observed that the Aux/IAA protein HaIAA27 represses transcriptional activation by HaHSFA9, a heat shock transcription factor (HSF). We also found that HaIAA27 is stabilized in immature sunflower embryos, where we could show bimolecular fluorescence complementation interaction between native forms of HaIAA27 and HaHSFA9. An auxin-resistant form of HaIAA27 was overexpressed in transgenic tobacco seeds, leading to effects consistent with down-regulation of the ortholog HSFA9 gene, effects not seen with the native HaIAA27 form. Repression of HSFs by HaIAA27 is thus likely alleviated by auxin in maturing seeds. We show that HSFs such as HaHSFA9 are targets of Aux/IAA protein repression. Because HaHSFA9 controls a genetic program involved in seed longevity and embryonic desiccation tolerance, our findings would suggest a mechanism by which these processes can be auxin regulated. Aux/IAA-mediated repression involves transcription factors distinct from ARFs. This finding widens interpretation of auxin responses.
