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
introductionVenetoclax represents a significant advancement in target anticancer therapy in the management of relapsed/refractory chronic lymphocytic leukemia (RR-CLL). This study aims to compare the efficacy and safety of the venetoclax + rituximab (VenR) regimen with other therapies approved in Brazil.
methodsA systematic review and network meta-analysis (NMA) was conducted to evaluate the efficacy and safety of treatments approved in Brazil for RR-CLL. Comprehensive literature searches were performed to identify randomized controlled trials. Risk of bias and certainty of evidence for each outcome were assessed across the included studies. The NMA was conducted using a frequentist framework. The primary efficacy outcomes were progression-free survival, overall survival, overall response rate, and time to next therapy. Safety was assessed on the basis of the incidence of serious adverse events.
resultsA total of 24 publications related to 12 trials were identified and included. VenR was associated with better survival outcomes when compared with standard regimens such as rituximab (HR 0.16; 95% CI 0.03-0.74) and physician choice (HR 0.17; 95% CI 0.04-0.81). In terms of progression-free survival, VenR achieved HR < 0.20, supported by narrow confidence intervals, when compared to treatments such as bendamustine plus rituximab, ofatumumab and physician choice, in addition to significantly favorable results compared to ibrutinib and acalabrutinib. Approximately half of the studies presented a low risk of bias, and the certainty of evidence assessed using the GRADE-NMA approach resulted in very low certainty of evidence, mainly due to risk of bias, intransitivity, and imprecision.
conclusionThis NMA provides valuable evidence to support rational therapeutic choices for RR-CLL in Brazil, highlighting VenR and Bruton tyrosine kinase inhibitors as leading treatment options across diverse clinical scenarios.
