1 · What the graph read from it

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.

2 · The registry

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

Malignant melanoma accounts for 75% of all skin cancer deaths and is potentially curable if identified early. Although melanoma is rare in African-Americans (AA), it is associated with a worse prognosis than in Caucasians. This study examines the demographic, pathologic, and clinical factors impacting AA melanoma outcomes.Data for 1106 AA and 212,721 Caucasian cutaneous melanoma patients were abstracted from the Surveillance, Epidemiology, and End Result (SEER) database (1988-2011). Data were grouped on the basis of histological subtypes: "Superficial Spreading" (SS), "Nodular" (NM), "Lentigo Maligna" (LM), "Acral Lentiginous" (AL), and "Not otherwise specified" (NOS).Cutaneous malignant melanoma occurs most commonly in the sixth and seventh decade of life. Caucasian patients presented most commonly with trunk melanomas (34.5%), while lower extremity melanomas were more common in AAs (56.1%), P < 0.001. AAs presented with deeper tumors, more advanced stage of disease, and higher rates of ulceration and lymph node positivity than Caucasians. Cancer-specific mortality was significantly higher, while 5-year cancer-specific survival was significantly lower among AAs for NM and AL subtypes. Multivariate analysis identified male gender, regional and distant stage, NM and AL subtypes as independently associated with increased mortality among both ethnic groups.AAs present most often with AL melanoma on the lower extremities, and with deeper and more advanced stage lesions. AAs have higher cancer-specific mortality for NM and LM than Caucasians. Melanoma education for AA patients and health care providers is needed to increase disease awareness, facilitate early detection, and promote access to effective treatment.
