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
Capacocha was a key Inca state rite that intertwined pilgrimage, sacrifice, and imperial incorporation across the Andes. We present a multianalytical investigation into two Capacocha cases from the western slope of the Andes: Cerro Esmeralda, located in the coastal Atacama Desert of northern Chile, and Cerro El Plomo, in the high mountains of central Chile. Stable isotope analysis reveals commensality practices during the pilgrimage, integrating local communities into the imperial order. Furthermore, computed tomography, dermatoscopy, and skin histology provide new evidence regarding the causes and mechanisms of death, identifying violent acts associated with sacrifice. Last, we present a pair of radiocarbon dates to discuss the chronology of both Capacocha contexts. In sum, these practices specify the materialization of Inca statecraft and contribute to characterizing the complexity and diversity of Capacocha ritual as an extension of the Inca biopolitical conquest.
