1 · What the graph read from it

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.

2 · The registry

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

Background: Olive pollen allergy, a leading cause of seasonal allergic rhinitis and asthma in Mediterranean regions, is becoming increasingly relevant worldwide due to the expansion of olive cultivation. Despite its significant public health impact, the molecular mechanisms underlying sensitization to olive pollen remain poorly understood. Methods: In this study, RNA sequencing was used to perform transcriptomic profiling on Results: A total of 37 differentially expressed genes (DEGs) were found exclusively in the patient group. Validation by RT-qPCR in an independent cohort confirmed the expression patterns of selected DEGs. Functional enrichment analyses associated these DEGs with immune pathways, ossification processes, and cytokine activity. Notably, upregulated genes such as Conclusion: Overall, this study provides new insights into the transcriptomic landscape of olive pollen allergy, identifying candidate biomarkers and biological pathways with translational relevance for improving diagnosis and advancing personalized treatment strategies in allergic diseases.
