Polatuzumab vedotin combined with bendamustine and rituximab for relapsed/refractory diffuse large B-cell lymphoma: A systematic review protocol.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDiffuse large B-cell lymphoma (DLBCL) is an aggressive non-Hodgkin lymphoma subtype with a significant relapse rate and poor prognosis in relapsed/refractory (R/R) patients. Polatuzumab vedotin in combination with bendamustine and rituximab (Pola-BR) has demonstrated promising efficacy and safety as salvage therapy for R/R DLBCL. This systematic review protocol aims to comprehensively evaluate the efficacy of Pola-BR for the treatment of R/R DLBCL by synthesizing data from relevant randomized controlled trials.
methodsThis protocol details the eligibility criteria, search strategy, study selection, data extraction, and analysis methods for the systematic review. Randomized controlled trials comparing Pola-BR with other interventions for R/R DLBCL will be included. The primary endpoint is overall survival, with secondary endpoints being progression-free survival and incidence of adverse events. A comprehensive search will be conducted across databases such as Medline/PubMed, Cochrane Library, Web of Science, Scopus, EMBASE, ProQuest, EU Clinical Trials Register, WHO International Clinical Trials Registry Platform (ICTRP), and ClinicalTrials.gov from the January 2000 to April 2024. To assess the potential risk of bias, the Cochrane Risk of Bias 1 tool will be used. Data synthesis will utilize fixed-effect or random-effects models, and subgroup and meta-regression analyses will examine heterogeneity. Additionally, publication bias and sensitivity analyses will be performed, and the GRADE approach will be applied to assess the certainty of the evidence.
conclusionThis systematic review and meta-analysis protocol provides a rigorous framework for evaluating the efficacy of Pola-BR in the treatment of R/R DLBCL. The results will inform clinical decision-making and guideline development, addressing the unmet need for effective and tolerable treatments for this challenging patient population. Potential limitations and biases will be acknowledged, and future research directions will be discussed.
