Diagnostic value of serum DR-70 levels, a new fibrin-related biomarker, in bladder cancer patients.
Article in BMC urology, 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
backgroundBladder cancer has high morbidity and mortality rates when it is diagnosed at an advanced stage. The aim of our study is to determine the effect of the DR-70 protein in the diagnosis of bladder cancer and to evaluate its relationship with the grade of the disease.
methodsSerum samples from 60 patients with bladder cancer and 24 control patients with macroscopic hematuria of benign etiology were included in the study. DR-70 levels were compared between the bladder cancer group and the control group. Additionally, a comparison was made between patients with non-muscle invasive bladder cancer and those with muscle invasive disease.
resultsThe median DR-70 level in the bladder cancer group was 1.08 U/mL (0.48-8.5), whereas it was 0.89 U/mL (0.29-1.76) in the control group. The DR-70 level was significantly greater in the bladder cancer group than in the control group (p = 0.012). DR-70 had a sensitivity of 73.3% and a specificity of 66.7% in detecting bladder cancer. On the other hand, the median DR-70 level was 1.06 U/mL (0.48-4.09) in patients with non-muscle-invasive bladder cancer (Ta, T1) and 2.66 U/mL (0.57-8.5) in patients with invasive bladder cancer (T2). DR-70 levels were significantly greater in patients with invasive bladder cancer than in those with non-muscle invasive bladder cancer (p = 0.021). Additionally, DR-70 had 72.7% sensitivity and 63.3% specificity in detecting muscle invasive bladder cancer.
conclusionsCompared with that in the control group, the protein level of DR-70 significantly increased in patients with bladder cancer and was greater in the group with muscle invasion.
