1 · What the graph read from it

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.

2 · The registry

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

Purpose: To evaluate the impact of perioperative blood transfusion (PBT) on oncologic outcomes after surgery in patients with nonmetastatic renal cell carcinoma (RCC). Materials and Methods: This retrospective review included 2,329 patients who underwent partial or radical nephrectomy for localized RCC in a single institution from 2000 to 2014. PBT was defined as transfusion of allogeneic packed red blood cells (pRBCs) during nephrectomy or within the preoperative or postoperative hospitalization period. Oncologic outcomes of interest were recurrence-free survival (RFS), overall survival (OS), and cancer-specific survival (CSS). Results: PBT was performed in 275 patients (11.8%). In the multivariable logistic regression analysis, symptomatic presentation, advanced age at surgery, higher preoperative serum creatinine, and lower preoperative hemoglobin were independent preoperative risk factors for PBT (all p<0.05). Kaplan-Meier plots revealed that transfused patients showed poorer 5-year RFS (65.1% vs. 91.2%, p<0.001), OS (71.4% vs. 92.8%, p<0.001), and CSS (74.0% vs. 95.5%, p<0.001) than nontransfused patients. However, in the multivariable Cox regression analyses, PBT was not significantly associated with RFS, OS, or CSS. In multivariable analyses involving transfused patients only (n=275), an higher number of pRBC units was an independent predictor of worse OS (hazard ratio [HR], 1.043; 95% confidence interval [CI], 1.008-1.078; p=0.016) and CSS (HR, 1.066; 95% CI, 1.033-1.100; p<0.001). Conclusions: The results of this study are inconclusive in that the influence of PBT on survival outcomes could not be determined in the multivariate analysis. However, increasing pRBC units in transfused patients might be a concern in light of worse OS and CSS. Therefore, efforts to limit PBT overuse seem necessary to improve postoperative survival in patients with RCC.
