Real-World Effectiveness and Safety of Pembrolizumab-Lenvatinib Versus Axitinib-Based Regimens in Metastatic Clear Cell Renal Cell Carcinoma: A Multicenter Retrospective Study.

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 compare the real-world effectiveness and safety of pembrolizumab plus lenvatinib with axitinib-based regimens (avelumab plus axitinib or pembrolizumab plus axitinib) as first-line therapy for metastatic clear cell renal cell carcinoma.
methodsWe retrospectively analyzed 107 patients treated with immuno-oncology plus vascular endothelial growth factor inhibitor combinations between 2017 and 2025. Propensity score matching (1:1, 0.2 caliper) generated 42 matched pairs. Objective response rate, progression-free survival, overall survival, and adverse events were assessed. Multivariable logistic regression and Cox regression analyses were performed in the overall cohort, and conditional logistic regression and stratified Cox regression analyses were applied in the matched cohort.
resultsIn the matched cohort, pembrolizumab plus lenvatinib demonstrated a significantly higher objective response rate than axitinib-based regimens. The incidence of any-grade and grade ≥ 3 adverse events was similar between regimens. However, pembrolizumab plus lenvatinib was associated with higher rates of hypertension (including grade ≥ 3 hypertension), fatigue, appetite loss, and rash in the full-dose subgroup. Progression-free and overall survival did not differ significantly. Multivariate analyses identified pembrolizumab plus lenvatinib treatment as an independent predictor of objective response, whereas survival outcomes were associated with clinical factors rather than the regimen type.
conclusionsPembrolizumab plus lenvatinib achieved a superior tumor response to axitinib-based regimens, whereas survival outcomes were comparable. Treatment selection should balance enhanced antitumor activity with differences in toxicity profiles.
