Predictors and Long-Term Outcomes for Diffuse Large B-Cell Lymphoma (DLBCL) Patients Undergoing Surgery Prior to Systemic Therapy: A Nationwide Analysis.
Article in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundA minority of patients diagnosed with diffuse large B-cell lymphoma (DLBCL) undergo surgery before the initiation of systemic therapy. The aim of this study is to explore the characteristics of patients undergoing surgery prior to systemic therapy (surgfirst), the predictors for surgfirst, and the survival outcomes.
methodsThe National Cancer Database was queried for patients with DLBCL diagnosed between 2006 and 2015, and we performed a subgroup analysis of patients that received surgfirst. Time-to-initial therapy (TTI) was defined as the time in days (d) from diagnosis to systemic therapy. Overall survival was measured from the day of diagnosis in terms of months (m).
resultsFactors associated with lower likelihood of surgfirst were non-Hispanic Black race (p-value<0.005), rural location (p-value<0.005), treatment at academic center (p-value<0.005), Medicaid insurance (p-value=0.01), comorbidity score >=3 (p-value 0.007), year of diagnosis, advanced stages of disease, and presence of B-symptoms. The TTI of systemic therapy was delayed in the surgfirst group - 34 (IQR 22-52) days vs. 23 (IQR 13-38) days, p-value<0.005. The five-year overall survival was 62.7% (95% CI 62.1-63.2%) vs. 58.3% (95% CI 57.7-60.0%) - HR 0.87 (95% CI 0.85-0.89), p-value<0.005. The factors associated with higher mortality were advanced comorbidities, lower educational status, disease primarily located in the bone, brain, and spinal cord, advanced clinical stage, presence of B-symptoms, and advanced age.
conclusionDespite the delay in systemic therapy, we could not identify a detrimental impact of surgfirst on survival. This needs to be confirmed in large-scale multicenter studies. We identified clinical and socioeconomic factors that affect treatment selection and survival.
