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

BACKGROUND AND

aimsSystemic inflammation is closely linked to the development and progression of various cancers, as well as poorer patient outcomes. The role of the c-reactive protein to albumin ratio (CAR) as a predictor of poor prognosis in renal cell carcinoma (RCC) remains insufficiently recognized.

methodsA literature search was conducted in major English-language databases, including PubMed, EMBASE, and the Cochrane Library, with the search updated to 25 June 2025. Both the odds ratio (OR) and diagnostic odds ratio (DOR) were employed to evaluate the prognostic performance of CAR.

resultsThis meta-analysis ultimately included 10 studies with a total of 2478 patients with RCC. The results showed that high baseline CAR was significantly associated with poor prognosis or recurrence of RCC. The sensitivity of 0.73 (95% confidence interval [CI]. 0.69-0.77); specificity of 0.69 (95% CI: 0.64-0.74) and DOR of 6.0 (95% CI: 5.0-8.0) were pooled estimated from patient-based analyses. Subsequently, the combined positive likelihood ratio (PLR) and negative likelihood ratio (NLR) were calculated with the results of 2.4 (95% CI: 2.0-2.8) and 0.39 (95% CI: 0.33-0.46), respectively. Furthermore, the area under the curve (AUC) of the summary receiver operating characteristic (SROC), which reflects prognostic accuracy, was 0.77 (95% CI: 0.73-0.81). In addition, subgroup analysis indicated that elevated CAR was more predictive of overall survival (OS) in RCC patients in China.

conclusionsOur findings indicate that an elevated CAR serves as a strong predictor of poor prognosis or recurrence in patients with RCC.
