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
Dormancy-Associated MADS-BOX (DAM)3 and DAM4 have been described as potential regulators of winter dormancy in cultivated strawberry (Fragaria x ananassa Duch.). These genes are upregulated under short-day conditions and downregulated under chilling conditions. The aim of the current work is to test the hypothesis that the expression of DAM3 and DAM4 correlates negatively with vegetative growth during dormancy induction and breaking. The expression of DAM3 and DAM4 as well as plant morphology and physiology was analyzed during a period of semi-dormancy induction and breaking. Furthermore, DAM3 and DAM4 expression was compared between cultivars with different chill requirements. Lastly, the DAM1, DAM2, DAM3, and DAM4 expression of concurrently growing summer and winter leaves was compared at multiple stages of dormancy breaking. DAM3 and DAM4 expression negatively correlated with leaf area and petiole length. We conclude that DAM3 and DAM4 expression patterns are consistent with that of regulators of semi-dormancy. DAM4 expression in particular correlates strongly with vegetative growth during semi-dormancy breaking. DAM3 or DAM4 expression was not found to correlate with the cultivar-specific chill requirements. Lastly, no relevant differences in DAM expression were found between summer and winter leaves.
