Drug induced hyperpigmentation: systematic review and meta-analysis.
Synthesis in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Drug-induced hyperpigmentation (DIH) represents a significant subset of acquired pigmentation disorders and poses diagnostic challenges due to delayed onset and polypharmacy. This systematic review and meta-analysis aimed to identify medications significantly associated with DIH and evaluate their reported incidence. Methods: A systematic search was conducted across PubMed, Scopus, Web of Science, and Cochrane Library for studies published between 2002 and June 2024. Eligible studies reported DIH as an outcome with incidence or descriptive data. Pooled proportions were calculated using a random-effects model, and heterogeneity was assessed via the I Results: Twenty-two studies met the inclusion criteria. The overall pooled incidence of DIH was 36.7% (95% CI: 0.291-0.444). Subgroup analyses revealed the highest incidences with tyrosine kinase inhibitors (89.2%) and MC4R agonists (71.4%), followed by antibiotics (52.0%), antineoplastic agents (35.5%), and antimalarials (29.0%). Commonly implicated agents included minocycline, hydroxychloroquine, and hydroxyurea. Conclusion: DIH is a prevalent adverse drug reaction with considerable variation in incidence across drug classes. Recognition of high-risk medications is essential for prompt diagnosis and clinical management. Systematic review registration: The study protocol was pre-registered in the International Prospective Register of Systematic Reviews (PROSPERO: CRD42024529250).
