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
Purpose: To explore the efficacy and safety of lenvatinib, either as a monotherapy or in combination with programmed death-1 (PD-1) blockades, as re-challenging treatment in patients with metastatic osteosarcoma following treatment failure with previous tyrosine kinase inhibitors (TKIs). Patients and Methods: We retrospectively reviewed the data of 26 patients with metastatic osteosarcoma who received rechallenge treatment with lenvatinib monotherapy or lenvatinib plus PD-1 blockades after failure of the initial TKI treatment from January 2020 to June 2024 in our center. The primary endpoint was progression-free survival (PFS). Secondary endpoints included objective response rate (ORR), clinical benefit rate (CBR), and safety. Results: Of the 26 patients, ORR and CBR were 11.5% and 61.5%, respectively. The median duration of follow-up was 15 months (range, 4.3-25.6) with a median PFS of 7.2 months (95% CI: 1.9-12.5). A total of 14 patients received lenvatinib as a monotherapy, and 12 received a combination therapy of lenvatinib and PD-1 blockade. No significant differences were observed in ORR (0 vs 25%) and CBR (57.1 vs 66.7%) between the two groups. Additionally, the combination cohort exhibited a significantly longer PFS compared to the monotherapy cohort (8.6 [95% CI: 5.0-12.1] vs 4.0 months [95% CI: 1.0-7.0], Conclusion: Our data indicated that patients with metastatic osteosarcoma could potentially benefit from lenvatinib rechallenge after progress with initial TKI treatment. The combination of lenvatinib and PD-1 blockade therapy demonstrated promising survival outcomes in patients with metastatic osteosarcoma, accompanied by a manageable toxicity profile.
