The prognostic value of visible hematuria is only significant in T1a renal cell carcinoma: a single-center retrospective study.
Article in BMC urology, 2024. 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
objectivesTo investigate the prognostic value of visible hematuria in T1a renal cell carcinoma (RCC). MATERIALS AND
methodsIn the RCC database of the Chinese People's Liberation Army General Hospital Department of Urology, we assembled the records of patients with unilateral RCC over 18 years of age diagnosed between 2008 and 2019. The clinical stage was cT1, and the tumors ranged in size from 0 to 7 cm. The primary treatments were partial nephrectomy (PN) or radical nephrectomy (RN). Logistic regression analysis, Cox regression, interaction analysis, and Kaplan-Meier survival analysis were used to study the correlation between visible hematuria and progression-free survival (PFS), and cancer-specific survival (CSS).
resultsA total of 7,610 patients with cT1 RCC comprised the study population, including 505 RCC patients with visible hematuria. The average follow-up time was 64.6 months (range: 12-144 months). Visible hematuria was significantly associated with the prognosis (PFS, hazard ratio [HR] = 2.7, P < 0.001; CSS, HR = 4.2, P < 0.001) of T1a RCC, but was more significant for CSS in cases of a tumor size ≤ 2 cm (HR = 26.8, P = 0.026). This effect was not significant in T1b RCC (PFS, HR = 0.7, P = 0.153; CSS, HR = 1.1, P = 0.862). The interaction between visible hematuria and tumor size was significant (P = 0.001).
conclusionsThis study showed that visible hematuria was an independent risk factor for PFS and CSS in T1a RCC. The predictive value of visible hematuria for CSS was more significant in RCCs ≤ 2 cm, but did not reach statistical significance in T1b RCC. T1a RCC patients with visible hematuria should be intensively monitored during follow-up.
