The neutrophil-to-lymphocyte ratio and the prevalence of cutaneous melanoma: a retrospective observational study of NHANES statistics spanning 1999 to 2018.
Observational study in Archives of dermatological research, 2025. 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
This study aimed to investigated the association between the ratio of neutrophils to lymphocytes (NLR) and cutaneous melanoma (CM) and to determine the association between the NLR and the prevalence of CM. A retrospective observational study involving 62,102 individuals over the age of 18, drawn from the National Health and Nutrition Examination Survey (NHANES), which was carried out over the period from 1999 to 2018. NLR derived from laboratory data, while CM diagnosis was based on participants' self-reports. The relationship between the NLR and CM was assessed using weighted logistic regression analyses, complemented by restricted cubic spline analyses. The study encompassed a total of 336 adults afflicted with CM and 49,621 adults free from CM. The findings exposed a correlation between the NLR and the occurrence of CM, having an odds ratio (OR) of 1.63 (95% confidence interval [CI]: 1.07 to 2.48; p = 0.022). Moreover, the restricted cubic spline model showed a non-linear pattern between the NLR and CM. Overall, we found that the NLR was positively associated with the prevalence of CM. Our findings highlight that NLR may be a systemic inflammation waring marker for CM in US individuals.
