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

Landform classification studies are prerequisites for recognizing regional geomorphic patterns and are urgently needed to explore the process of landform development and evolution. Taking the Tibetan Plateau as the study area, this paper proposes new geomorphologic classification methods and indicators, such as slope-cost distance and mountain undulation, considering the global topographic features and the integrity of geomorphologic objects. On this basis, the classification of geomorphic types on the Tibetan Plateau was completed. The results show that: (1) The proportion of plains within the mountainous Tibetan Plateau has reached 25%, with the ratio of the mountain and plain areas close to 3:1, and the mountain types are dominated by low-relief mountains and middle-relief mountains. (2) The spatial distribution of the plains is characterized by high fragmentation and low spatial aggregation, with an overall dispersed distribution "from inside to outside". (3) The mountains form an overall topographic skeleton of "three horizontal and one vertical" and the global landform pattern of the Tibetan Plateau is complex and diverse. The outcomes can provide a reference for digital terrain analysis and landform classification-related studies.
