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
backgroundThe scalp has a higher sebum content than other body areas, leading to issues such as itchiness, dandruff and discomfort. In individuals with scalp seborrhoea, the relationships between sebum levels, hydration, barrier function and self-perceived scalp condition remain poorly understood.
aimsThis study aimed to explore scalp sebum accumulation and associated physiological properties, as well as to evaluate the impact of a single shampoo cleansing efficacy on sebum levels.
methodsThis study involved an Asian population with self-reported scalp oiliness and dandruff. Participants with elevated scalp sebum levels (>75 µg/cm
resultsAt baseline, the scalp exhibited higher sebum levels, lower hydration and weaker barrier function compared to the frontal hairline and nape. Scalp hydration negatively correlated with sebum levels measured in scalp pores. Hydroxyoctadecadienoic acid (HODE), an oxidative stress biomarker, positively correlated with scalp sebum. Interestingly, HODE levels also showed a positive correlation with participants' self-reported dandruff and itchiness. After single wash with a shampoo containing 0.5% piroctone olamine (PO), surface and pore sebum levels were significantly reduced, as well as HODE levels.
conclusionThis study underscores the significance of sebum levels and composition in scalp health among Chinese individuals, emphasizing the need for shampoos that remove excess sebum while preserving the scalp barrier.
