Observational studyAnais brasileiros de dermatologia
Clinical and epidemiological characterization of patients with cutaneous tuberculosis treated at a referral center in the Brazilian Amazon: case series.
Observational study in Anais brasileiros de dermatologia. 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
backgroundCutaneous tuberculosis is a rare form of the disease that defies diagnosis due to the diversity of clinical presentations. This study was based on the reality of a dermatology referral center in the Brazilian Amazon region to detail several characteristics of this disease.
objectiveTo describe a series of cases of cutaneous tuberculosis treated at a dermatology service in the Brazilian Amazon region, addressing epidemiological aspects, clinical forms, diagnostic methods, treatment, and outcomes.
methodsThis is a descriptive and observational study of the case series type, including eight patients with a confirmed diagnosis of cutaneous tuberculosis seen between 2021 and 2023. A standardized protocol was used to collect data from patients' medical records.
resultsAmong the eight cases of cutaneous tuberculosis, there were four cases of erythema induratum of Bazin, one case of tuberculosis verrucosa cutis, two cases of scrofuloderma, and one case of lupus vulgaris. Erythema induratum of Bazin, the most common form in the study, occurred predominantly in women, presenting as infiltrated plaques and erythematous nodules. All eight cases were treated with the standard therapeutic regimen of the Brazilian Ministry of Health (rifampicin, isoniazid, pyrazinamide, and ethambutol). STUDY LIMITATIONS: They include the small sample size, making generalizations difficult.
conclusionsThe study addressed the clinical diversity of cutaneous tuberculosis, with erythema induratum of Bazin as the most common form. The importance of the socioeconomic context in the prevalence of the disease and the need for more comprehensive epidemiological studies to improve the understanding of cutaneous tuberculosis, especially in endemic regions, are highlighted.
