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 compounds present in yerba mate are related to the climatic, cultivation, and production factors. The study aimed to analyze the effects of production factors, environmental, and cropping systems on the elementary composition and physicochemical properties of yerba mate postharvest in the different regions of Southern Brazil. Among the factors evaluated are the age of the yerba mate plantation, shading, type of pruning, soil characteristics, use of fertilizers, and cleaning practices of the yerba mate plantation. The results indicated that the different cultivation and management conditions of yerba mate interconnected influenced its physical-chemical and elemental composition. The interactions between minerals such as Mg, Ca, Mn, Co, and V were predominantly positive. Yerba mate plantations over 21 years old presented the highest Aluminum and Arsenic contents. The color of yerba mate was mainly influenced by the green and yellow tones, varying according to the age of the yerba mate, the type of pruning, the use of fertilizers, and the cleanliness of the cultivation area. However, the caffeine and saponin content stood out, presenting variations in all conditions analyzed. The postharvest quality of yerba mate was closely related to agricultural practices and specific environmental conditions, mainly the age of the yerba mate and the type of pruning.
