Patterns and Geographical Mechanism of Altitudinal Belts in Tropical African Mountains.

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
Altitudinal belts exhibit substantial variation across the world's mountains in number, typology, combination patterns, and vertical range. However, the conditions under which specific belts occur and the climatic factors influencing their vertical range remain poorly understood. Therefore, this study focuses on tropical African mountains, which are characterized by massive volcanic cones, rich biodiversity, and complete altitudinal belt structure, as a representative region. We compiled 23 spectra of altitudinal belts from published literature for 10 representative tropical African mountains. Integrating climatic data of WorldClim V2.0 and topographic data from SRTM 90 m DEM, we investigated the vertical ranges and combination structures of altitudinal belts, and analyzed their relevant driving climatic factors using stepwise regression. The results show that: (1) Tropical African mountains usually have five to eight altitudinal belts which constitute a complete altitudinal belt spectrum from tropical vegetation to nival zones. (2) The upper montane regions are typically characterized by the development of bamboo forest, cloud forest, and ericaceous forest belts, but with different patterns of single belt, dual belts and triple belts. (3) Climate-altitudinal belt regression models could well explain the vertical range of the highest forest belts (ericaceous forest) and low forest belt (monsoon rainforest) (
