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
BACKGROUND/
objectivesPost-inflammatory hyperpigmentation (PIH) is a frequent sequela of acne in patients with skin of colour (SOC). While sunscreen is widely recommended for PIH prevention, little is known about real-world sunscreen practices in this group. This study aimed to evaluate sunscreen use, barriers and factors influencing adherence in SOC patients with acne-related PIH.
methodsA cross-sectional survey was conducted on 51 SOC patients (FST III-VI) who attended a dermatology clinic in Australia between February and June 2025. An investigator-developed questionnaire assessed sunscreen use frequency, reapplication, application amount, tinted sunscreen uptake, and perceived barriers. Associations were examined using chi-square/Fisher's exact tests and logistic regression analyses. Analyses were exploratory.
resultsDaily sunscreen use was inconsistent, with 39.2% applying occasionally (< 3 times/week) and only 33.3% applying daily. Reapplication was inadequate, with 57.5% (23/40) reapplying only when outdoors for prolonged periods. Most patients (79.5%, 31/39) applied less than one finger-length to the head and neck. Tinted sunscreen uptake was low, though shade match was a key determinant of adherence among users. Few patients recognised sunscreen's role in PIH prevention (19.6%), with professional advice emerging as an important factor associated with correct belief (no advice vs. advice, OR 0.04, p = 0.01).
conclusionsSunscreen use among SOC patients with acne-related PIH was suboptimal, with inadequate daily use, reapplication, and quantities applied. Clinician-led education was a key factor in influencing patient beliefs, highlighting the need for targeted counselling. Expanding shade-diverse, cosmetically elegant, tinted formulations may further improve adherence in SOC populations.
