Incidental and symptomatic renal tumors: impact on patient survival.
Article in Sao Paulo medical journal = Revista paulista de medicina, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
contextRenal cell carcinoma is the third most frequent genitourinary neoplasia, and there is currently an increase in the incidental diagnosis of tumors confined to the kidneys.
objectiveTo study the survival of patients with incidental and symptomatic renal tumors who have undergone nephrectomy.
designRetrospective.
settingHospital Sírio Libanês and Hospital Beneficência Portuguesa de São Paulo.
participants115 patients with diagnosis of renal cell carcinoma, operated on by the same group of surgeons and evaluated by a single pathologist. MAIN MEASUREMENTS: Sex, age and diagnosis method, analyzed in two groups, according to the tumor diagnosis: Group 1 with incidental diagnosis and Group 2 with symptomatic tumors. The anatomopathological characteristics and patient survival in both groups were evaluated. A statistical analysis was performed using the Student t, chi-squared, log rank and Kaplan-Meyer tests.
resultsAmong the studied patients, 59(51%) had an incidental diagnosis, with 78% diagnosed by ultrasonography, 20% by computerized tomography scan and 2% during surgeries; 56 patients (49%) were symptomatic. Tumor locations were equally distributed between the two kidneys, and the surgery was conservative for 24% of the incidental and 9% of the symptomatic group. In the incidental group only one patient had tumor progression and there was no death, while in the symptomatic group there were 5 progressions and 10 deaths. The 5-year specific cancer-free survival was 100% in the incidental and 80% in the symptomatic group (p = 0.001) while the disease-free rate was 98% in the incidental and 62% in the symptomatic group (p < 0001).
conclusionIncidental renal tumor diagnosis offers better prognosis, providing longer disease-free survival.
