Role of rituximab in treatment of patients with primary central nervous system lymphoma: An updated systematic review and meta-analysis.

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
backgroundPrimary central nervous system lymphoma (PCNSL) is a rare and aggressive form of extranodal non-Hodgkin lymphoma, most often a diffuse large B-cell lymphoma. Rituximab, an anti-CD20 monoclonal antibody is widely used in PCNSL treatment but its efficacy remains uncertain. Therefore, we conducted a systematic review and meta-analysis to assess the efficacy of rituximab in newly diagnosed adult PCNSL patients.
methodsMedline/PubMed and Scopus were searched for studies comparing rituximab/rituximab-containing regimens with therapies not including rituximab in adult PCNSL patients. A random-effects meta-analysis was conducted, and risk ratios (RR) and hazard ratios (HR) were reported with 95% confidence interval (CI). Outcomes included 3- and 5-year overall survival (OS), OS independent of time, 3- and 5-year progression-free survival (PFS), and complete response (CR).
resultsSixteen studies (three RCTs, thirteen retrospective) with 2,325 patients (rituximab: 1010; control: 1315) were included. Rituximab-containing therapy was significantly associated with higher 3-year OS (RR: 1.37; 95% CI: 1.07-1.76), higher CR rate (RR: 1.37; 95% CI: 1.05-1.79) and reduced hazard of death (HR: 0.65; 95% CI: 0.43-0.98). 3-year PFS showed a non-significant trend favoring rituximab (RR: 1.29; 95% CI: 0.99-1.68) which reached statistical significance in sensitivity analysis after excluding one study (RR: 1.40; 95% CI: 1.12-1.77). No statistically significant differences were observed for 5-year OS (RR: 1.33; 95% CI: 0.99-1.78) or 5-year PFS (RR: 1.24; 95% CI: 0.79-1.94) between the two groups.
conclusionOur findings indicate that rituximab-containing therapy was associated with improved short-term outcomes in newly diagnosed adult PCNSL. However, long-term advantages remain uncertain. Therefore, there is a need for larger randomized trials with standardized outcome and toxicity reporting and extended follow-up to confirm long-term survival benefit.
