The metaxenia effects of different pollen grains on secondary metabolites enzymes and sugars of 'Piarom' date palm fruit.
Article in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
In this research, the characteristics of pollen were studied in eight pollinating cultivars of date palm, namely, 'Shahani', 'Kabkab', 'Zahedi', 'Beraem', 'Faryab', 'Sheikhali', 'Fard' and 'Jarvis'. The characteristics were compared and metaxenia effects were evaluated on secondary metabolites, enzymes and other biochemical compounds of 'Piarom' date fruits. The evaluations were carried out during four stages of fruit growth and development. The pollen of these eight pollinating cultivars were compared in terms of carbohydrates, proteins, starch, total phenol, flavonoids, pectin methyl esterase, and amylase enzymes. According to the results, the pollen of 'Sheikhali', 'Fard', 'Zahedi' and 'Shahani' cultivars contained more of the above compounds, compared to the other cultivars. Regarding the effects of pollen on the composition of 'Piarom' date fruits, 'Fard' and 'Sheikhali' pollen produced the lowest amount of soluble tannin, which resulted in a better quality of 'Piarom' date fruits. Pollen was also obtained from 'Sheikhali' and 'Fard' cultivars for evaluations, showing that they led to the highest amounts of glucose and fructose in the fruits. Regarding the sucrose amount, 'Jarvis' and 'Shikhali' produced the best results. Pollen of 'Sheikhali' and 'Fard' cultivars caused the lowest amount of chlorophyll at the different stages of fruit growth, indicating a better decomposition of fruit chlorophyll and, as a result, better fruit quality. Pollen of 'Sheikhali' and 'Fard' cultivars produced the highest amounts of secondary metabolites such as total phenol, carotenoids and anthocyanin at the different stages of fruit development. The pollen of 'Fard' and 'Sheikhali' cultivars produced the highest levels of polygalacturonase, cellulase and invertase enzymes at different growth stages of the 'Piarom' date fruit. Regarding cellulase enzyme, fruits of the 'Zahedi' cultivar had more cellulase than the fruits of 'Sheikhali'. In general, the pollen of 'Fard' and 'Sheikhali, in comparison with other cultivars, improved the quantity and quality of 'Piarom' date fruits, due to their metaxenia properties.
