Complications after sentinel node biopsy and inguinal lymph node dissection in penile cancer: a Danish national cohort study.

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
purposeSentinel node biopsy (SNB) and inguinal lymph node dissection (ILND) are central to penile cancer management, but ILND especially carries substantial morbidity. This nationwide study explores the extent and risk factors of postoperative complications after inguinal lymph node surgery in Danish penile cancer patients.
methodsWe conducted a retrospective cohort study of penile cancer patients diagnosed in Denmark 2013-2025. Surgical procedures, pathological outcomes, and complications were extracted from medical records. Univariable and multivariable logistic regression with multiple imputation was used to assess predictors of complications.
resultsAmong 745 patients, 717 underwent 1348 SNB procedures and 184 underwent 241 ILND procedures. Postoperative morbidity increased substantially with procedural extent, with complications occurring after 9% of SNB procedures and after 31% of ILND procedures. Lymphoedema developed in 47% of patients following ILND versus 9% following SNB. Increasing lymph node yield independently predicted overall complications within both SNB and ILND cohorts and was additionally associated with wound infection following SNB. For lymphoedema, ILND carried five- to nine-fold higher odds compared with SNB, while higher BMI independently predicted lymphoedema risk (OR 1.07 per kg/m
conclusionComplications increase markedly with procedure extent. Increasing lymph node yield was associated with wound infection, while lymphoedema is primarily determined by procedure type. Poor predictive ability of patient characteristics limits pre-operative risk stratification.
