The distribution of bioactive gibberellins along peach annual shoots is closely associated with PpGA20ox and PpGA2ox expression profiles.
Article in BMC genomics, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundThe rapid growth of annual shoots is detrimental to peach production. While gibberellin (GA) promotes the rapid growth of peach shoots, there is limited information on the identity and expression profiles of GA-metabolism genes for this species.
resultsAll six GA biosynthetic gene families were identified in the peach genome, and the expression profiles of these family members were determined in peach shoots. The upstream biosynthetic gene families have only one or two members (1 CPS, 2 KSs, and 1 KO), while the downstream gene families have multiple members (7 KAOs, 6 GA20oxs, and 5 GA3oxs). Between the two KS genes, PpKS1 showed a relatively high transcript level in shoots, while PpKS2 was undetectable. Among the seven KAO genes, PpKAO2 was highly expressed in shoots, while PpKAO1 and - 6 were weakly expressed. For the six GA20ox genes, both PpGA20ox1 and - 2 were expressed in shoots, but PpGA20ox1 levels were higher than PpGA20ox2. For the five GA3ox genes, only PpGA3ox1 was highly expressed in shoots. Among these biosynthesis genes, PpGA20ox1 and PpGA3ox1 showed a gradual decrease in transcript level along shoots from top to bottom, and a similar trend was observed in bioactive GA
conclusionsOur results suggest that PpGA20ox and PpGA2ox expression are closely associated with the distribution of active GA
