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

The evolution of a large intracratonic rift trough in the northern Sichuan Basin, China, along the northwestern margin of the Yangtze Block, is documented during the significant Ediacaran-Cambrian Transition (ECT). Three prevailing perspectives exist regarding the specific genesis of this rift: the inherited development of rift basins, erosional troughs, and tensional erosional troughs. However, the dynamic mechanisms underlying rift trough development and the precise timing of this transition remain contentious. Consequently, this paper conducts a systematic geochemical and chronological investigation for the first time, utilizing siliceous sediments from the Dengying Formation and detrital zircons from the Cambrian Canglangpu Formation. Detrital zircons are used to constrain the Neoproterozoic tectonic evolution of the northwestern Yangtze Block, and geochemical records of siliceous sediments are adopted to reconstruct the evolutionary history of the rift trough. The study's results indicate the following: 1. Neoproterozoic zircons in the study area are dominated by continental arc signatures, with features of arc-associated orogenic compression and partially depleted mantle affinities. Crustal thickness variations calculated from zircon Eu/Eu* ratios indicate that arc-related extensional rifting occurred in the study area after ∼650 Ma. 2. The δ
