Prediction of distant metastases in penile squamous cell carcinoma: a SEER population-based study.
Article in International urology and nephrology, 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
Due to the limited number of patients with penile cancer, there is currently no prospective randomized study on patients with penile cancer, especially on patients with distant metastasis of penile cancer. The objective of this study was to develop a nomogram based on a large cohort to predict the probability of distant metastasis in patients with penile squamous cell carcinoma. 1453 patients were included in our study. Univariate and multivariate logistic regression analyses were employed to identify the independent variables, which were used to construct a nomogram. In this nomogram, high grade, high N stage, and primary site surgery (OR 0.354, 95% CI 0.146-0.859) were predictors of distant metastasis in patients with penile squamous cell carcinoma. The area under the curve (AUC) for internal validation of this nomogram was 0.880. Incisional biopsy of regional lymph nodes had been demonstrated to be associated with a poorer survival prognosis in patients with one distant metastatic site. Furthermore, patients with two metastases had a significantly worse survival rate than those with a single metastasis. These findings may prove instrumental in the surgical decision-making process.
