Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Amid the ongoing trend of global warming, the distribution of habitable areas for Rhododendron is facing significant risks. To investigate the possible spatial distribution of Rhododendron on the Qinghai-Xizang Plateau in light of future global warming scenarios, we employed the Maximum entropy model (MaxEnt model) to map its suitable habitat using geographic distribution data and environmental factors projected for 2050s and 2070s, considering three representative concentration pathway (RCP) scenarios, while identifying the key factors influencing their distribution. The results show that: [1] The area under curve (AUC) values of the five Rhododendron were all greater than 0.98, indicated that the model prediction effect was excellent; [2] Isothermality is the most important environmental factor affecting the distribution of Rhododendron (excluding Rhododendron przewalskii). The most important environmental factor for Rhododendron przewalskii is altitude (alt: 51%), with an optimum range of 2700-3300 m, and Rhododendron trichostomum are affected by altitude (alt 18%), with an optimum range of 3200-3900 m. Rhododendron przewalskii (bio12: 21%) and Rhododendron trichostomum(bio12: 19%) are also affected by annual precipitation, and Rhododendron laudandum(bio12: 6%) is less affected by annual precipitation, The optimal amount of precipitation is 400-500 mm as well as 500-800 mm. Rhododendron przewalskii and Rhododendron trichostomum are suitable for survival in high altitude, semi-arid areas [3]. The suitable areas for survival for Rhododendron przewalskii, Rhododendron trichostomum, Rhododendron hypenanthum, and Rhododendron nyingchiense is expanding, while the suitable areas for survival for Rhododendron laudandum is shrinking [4]. The optimal zone for Rhododendron przewalskii is primarily found in the eastern section of the Qinghai-Xizang Plateau, while suitable areas for survival for the other four Rhododendron species are predominantly located in the southern region of the same plateau. Therefore, these regions will be designated as the primary conservation zones for in-situ preservation. The results of the study provide a basis for the in situ conservation of Rhododendron in response to global warming, relocation conservation, and the construction of nature reserve communities and ecological corridors.
