Investigation of Hair Diseases Accompanying Bitemporal Alopecia: An Observational Cross-Sectional Study.
Article in Journal of clinical practice and research, 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
Objective: Bitemporal alopecia may occur in association with various hair diseases. However, it has not yet been officially classified as a distinct type of alopecia. This study aimed to identify hair diseases that commonly accompany bitemporal hair loss and to evaluate the clinicodemographic characteristics of affected patients. Materials and Methods: This study included 86 patients aged ≥18 years with bitemporal alopecia. Clinicodemographic characteristics and concomitant hair diseases were recorded. The severity of bitemporal alopecia was classified into three categories: mild, moderate, and severe. Results: The mean age of the patients was 36.2±15.7 years. Of the participants, 58.1% were female and 41.9% were male. Most patients were in the 18-24 (29.1%) and 25-34 (25.6%) age groups. A positive hair pull test was observed in 45 patients. Bitemporal alopecia was classified as mild in 22 patients (25.6%), moderate in 40 patients (46.5%), and severe in 24 patients (27.9%). Hair diseases accompanying bitemporal alopecia included androgenetic alopecia (n=57, 66.3%), seborrheic dermatitis (n=38, 44.2%), telogen effluvium (n=29, 33.7%), traction alopecia (n=11, 12.8%), lichen planopilaris (n=5, 5.8%), alopecia areata (n=3, 3.5%), frontal fibrosing alopecia (n=2, 2.3%), and anagen effluvium (n=1, 1.2%). The most frequent coexisting conditions were androgenetic alopecia (25.6%), androgenetic alopecia with seborrheic dermatitis (25.6%), seborrheic dermatitis with telogen effluvium (9.3%), androgenetic alopecia with telogen effluvium (8.1%), seborrheic dermatitis with telogen effluvium and traction alopecia (5.8%), and other combinations. Conclusion: Bitemporal alopecia may serve as a potential predictive indicator for the diagnosis and follow-up of associated hair diseases.
