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
Objectives: The aim of this study was to determine the potential benefit of perioperative systemic therapy on overall and progression-free survival after repeat local treatment in patients suffering from recurrent colorectal cancer liver metastasis (CRLM). Background: The optimal treatment strategy in patients with recurrent CRLM needs to be clarified, in particular for those suffering from early recurrence of CRLM. Methods: In this multicenter observational cohort study, consecutive patients diagnosed with recurrent CRLM between 2009 and 2019 were retrospectively identified in 4 academic liver surgery centers. Disease-free interval after initial local treatment of CRLM was categorized into recurrence within 6, between 6 and 12, and after 12 months. Perioperative systemic therapy consisted of induction, (neo)adjuvant, or combined regimens. Overall and progression-free survival after repeat local treatment of CRLM were analyzed by multivariable Cox regression analyses, resulting in adjusted hazard ratios (aHRs). Results: Out of 303 patients included for analysis, 90 patients received perioperative systemic therapy for recurrent CRLM. Favorable overall (aHR, 0.45; 95% confidence interval [CI], 0.26-0.75) and progression-free (aHR, 0.53; 95% CI, 0.35-0.78) survival were observed in patients with a disease-free interval of more than 12 months. No significant difference in overall and progression-free survival was observed in patients receiving perioperative systemic therapy at repeat local treatment of CRLM, stratified for disease-free interval, previous exposure to chemotherapy, and Conclusions: No benefit of perioperative systemic therapy was observed in overall and progression-free survival after repeat local treatment of recurrent CRLM.
