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
Quantitative real-time PCR (RT-qPCR) is one of the most accurate methods for gene expression analysis. An important step in such an examination is normalization of the results by the application of appropriate internal control. In this study, we evaluated ten candidate reference genes in wheat (Triticum aestivum) to identify the most stable for normalization across different tissues and organs of developing plants. In Experiment 1, ten reference genes were analyzed in three tissues of the Ostka cultivar, with stability rankings generated using BestKeeper, NormFinder, geNorm, and RefFinder. Among these, Ta2776, eF1a, Cyclophilin, Ta3006, Ta14126, and Ref 2 were consistently identified as the most stable, while β-tubulin, CPD, and GAPDH were the least stable. In Experiment 2, six reference genes were tested across five tissues. Ta2776, Cyclophilin, Ta3006, and Ref 2 showed high stability across tissues, whereas CPD and Actin were less reliable. Analysis of the two best performing genes, Ref 2 and Ta3006, in twelve tissues/organs from two wheat cultivars, Kontesa and Ostka, revealed no significant differences in their expression between cultivars, confirming their suitability as reference genes for broader studies. Expression analysis of two target, developmentally expressed genes, TaIPT1 and TaIPT5, was conducted using absolute and normalized values. For TaIPT1, expressed in developing spikes, normalized and absolute values showed no significant differences. In contrast, for TaIPT5, expressed across all tested tissues, significant differences were observed between absolute and normalized values in most tissues. However, normalization using Ref 2, Ta3006, or both reference genes produced consistent results, underscoring the importance of proper reference gene selection. This study highlights the reliability of Ref 2 and Ta3006 as reference genes for accurate normalization in wheat gene expression analyses, providing a robust framework for future research.
