Development and validation of a clinico-histological factor-based nomogram for survival in sinonasal malignancies.
Article in Scientific reports, 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
The survival prognosis nomogram is needed for sinonasal malignancies with different histology types. Thus this research collected cases with sinonasal malignancies from The Surveillance, Epidemiology, and End Results (SEER) program. R was the tools for screening the predictors by Accelerated Failure Time model and "backward" elimination. Nomogram was constructed with predictors. C-index, calibration curves and decision curve analysis were applied for the validation of the nomogram. 5795 cases were collected for constructing nomogram. "Age", "Sex", "Marriage", "Site", "AJCC", "Surg", "Radiation", and "Hist" were retained as predictors. The C-index was 0.77 (95% CI: 0.76-0.79, validation set). Calibration curves were close to the diagonal line. Decision curve analysis showed nonmogram provided positive net benefits relative to the default "treat-all" and "treat-none" approaches. We also conducted survival analysis for seven histology types with treatment (squamous cell carcinoma, adenocarcinoma, adenoid cystic carcinoma, undifferentiated carcinoma, primary mucosal melanoma, neuroendocrine carcinoma, olfactory neuroblastoma ). In conclusion, we constructed a nomogram to predict the survival prognosis of patients with sinonasal malignancies. It can be utilized by clinicians to predict individual survival outcomes and for patient consultation. Besides, we provided survival status for seven histology types of sinonasal malignancies with common and controversial treatment.
