Prognostic value of the ratio of maximum to minimum diameter of primary tumor in metastatic clear cell renal cell carcinoma.
Article in BMC urology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundSeveral models and markers were developed and found to predict outcome of advanced renal cell carcinoma. This study aimed to evaluate the prognostic value of the ratio of maximum to minimum tumor diameter (ROD) in metastatic clear cell renal cell carcinoma (mccRCC).
methodsPatients with mccRCC (n = 213) treated with sunitinib from January 2008 to December 2018 were identified. Cutoff value for ROD was determined using receiver operating characteristic. Patients with different ROD scores were grouped and evaluated. Survival outcomes were estimated by Kaplan-Meier method.
resultsThe optimal ROD cutoff value of 1.34 was determined for progression free survival (PFS) and overall survival (OS). Patients in ROD ≥ 1.34 group had shorter PFS (9.6 versus 17.7 months, p < 0.001) and OS (25.5 versus 32.6 months, p < 0.001) than patients in ROD < 1.34 group. After adjustment for other factors, multivariate analysis showed ROD ≥ 1.34 was an independent prognostic factor for PFS (p < 0.001) and OS (p = 0.006). Patients in ROD ≥ 1.34 group presented higher proportions of pT3/4 stage (89.2% versus 10.8%, p = 0.021), WHO/ISUP grade III/IV (72.0% versus 28.0%, p = 0.010), tumor necrosis (71.0% versus 29.0%, p = 0.039), sarcomatoid differentiation (79.1% versus 20.9%, p = 0.007), poor MSKCC risk score (78.4% versus 21.6%, p < 0.001) and poor IMDC risk score (74.4% versus 25.6%, p < 0.001) than ROD < 1.34 group.
conclusionPrimary tumor with higher ROD was an independently prognostic factor for both PFS and OS in patients with mccRCC who received targeted therapy. Higher ROD was also associated with high pT stage, high WHO/ISUP grade, sarcomatoid features, tumor necrosis, poor MSKCC and IMDC risk score.
