Prognostic value of serum uric acid levels following radiotherapy and chemotherapy in nasopharyngeal carcinoma.

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
To evaluate the association between serum uric acid (SUA) levels and prognosis in patients with nasopharyngeal carcinoma (NPC) treated with a comprehensive regimen of induction chemotherapy, intensity-modulated radiation therapy (IMRT), and adjuvant chemotherapy. A total of 182 patients with NPC treated at the Second Affiliated Hospital of Nanchang University between 2017 and 2021 were retrospectively analyzed. SUA levels were recorded at four time points: Pre-treatment, post-induction chemotherapy, post-IMRT and post-adjuvant chemotherapy. Based on the median post-adjuvant chemotherapy SUA level (350.48 µmol/l), patients were stratified into high (SUA >350 µmol/l) and low (SUA ≤350 µmol/l) groups. Survival outcomes were compared using Kaplan-Meier analysis and log-rank tests. Cox proportional hazards models were employed to identify independent prognostic factors. Changes in SUA levels over time were assessed using repeated-measures ANOVA. The high SUA group demonstrated improved 3-year overall survival (OS; P=0.037), progression-free survival (PFS; P<0.001), and distant metastasis-free survival (DMFS; P=0.001) compared with the low SUA group. No significant difference in locoregional relapse-free survival (P=0.41) was observed. Post-adjuvant chemotherapy SUA levels were an independent prognostic factor for OS, PFS and DMFS. Repeated-measures ANOVA showed a significant reduction in SUA levels post-IMRT compared with baseline, post-induction chemotherapy, and post-adjuvant chemotherapy (all P<0.001). In conclusion, elevated post-adjuvant chemotherapy SUA levels are associated with improved survival outcomes in patients with advanced-stage NPC. IMRT induces a transient decrease in SUA levels. These findings suggested that SUA levels may serve as a valuable prognostic biomarker for NPC.
