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

Pinus pumila needles are an underexplored source of essential oils with promising bioactivities; however, the conventional hydrodistillation (HD) method is inefficient and may promote the degradation of terpenoid compounds during extraction. In this study, an integrated ultrasound pretreatment and microwave-assisted hydrodistillation (UP-MAH) method was applied to extract P. pumila needle essential oil (PNEO), and the extraction process was optimized using response surface methodology. Under the optimal conditions, UP-MAH yielded 3.81% PNEO, corresponding to a 35.11% increase compared with HD, while also reducing energy consumption and CO
