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
Among the five phytochromes in Arabidopsis thaliana, phytochrome A (phyA) plays a major role in seedling deetiolation. Mutant analyses have identified more than 10 positive components acting downstream of phyA to inhibit hypocotyl elongation. However, their sites of action and their hierarchical relationships are poorly understood. Here, we investigated the genetic and molecular relationship between two homologous proteins, FAR-RED ELONGATED HYPOCOTYL1 (FHY1) and FHY1-LIKE (FHL), and two transcription factors, LONG AFTER FAR-RED LIGHT1 (LAF1) and LONG HYPOCOTYL IN FAR-RED1 (HFR1). Analyses of double and triple mutants showed that LAF1, a myb factor, and HFR1, a basic helix-loop-helix factor, independently transmit phyA signals downstream of FHY1 and FHL. Coimmunoprecipitation experiments showed that phyA, FHY1, FHL, LAF1, and HFR1 are components of protein complexes in vivo. In vitro pull-down assays demonstrated direct interactions between partner proteins with the N-terminal region of FHY1, as well as that of FHL, interacting with the LAF1 N-terminal portion and the HFR1 C-terminal region. These results suggest that, in addition to assisting phyA nuclear accumulation, FHY1 and FHL are required to assemble photoreceptor/transcription factor complexes for phyA signaling.
