The optimal timing and courses of bevacizumab added to chemotherapy for non-squamous non-small cell lung cancer: revelations from the real-world experience in a single Chinese cancer center.

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
backgroundBevacizumab combined with platinum-based chemotherapy has been approved in the first-line treatment for advanced non-squamous non-small cell lung cancer (NSCLC) without driver genes, but this regimen for second-line or later-line treatment of non-squamous NSCLC remains to be further tested. Our study aimed to provide data on the safety and effectiveness of bevacizumab (Bev)-containing chemotherapy in different-line settings for patients with NSCLC in the Chinese real-world clinical routine practice and to explore predictors for progression-free survival (PFS) and overall survival (OS).
methodsWe reviewed the medical records of 194 patients with non-squamous NSCLC who received Bev plus chemotherapy as the first-, second- or third- or later-line treatment between December 2009 and January 2020 at Fudan University, Shanghai Cancer Center. Clinical characteristics, treatment history, clinical evaluation, and adverse effects of each patient were deeply analyzed. PFS and OS were estimated by the Kaplan-Meier method. Univariate and multivariate analyses were conducted to find predictors of longer PFS and OS.
resultsOne hundred ninety-four patients were enrolled in this study, including 102 (52.6%), 58 (29.9%) and 34 (17.5%) patients received Bev in combination with the first-line chemotherapy (Bev + Che1), second-line chemotherapy (Bev + Che2) and third-/later-line chemotherapy (Bev + Che3), respectively. Administration of Bev in combination with the first-line chemotherapy and >6 courses were independent predictors of significantly prolonged PFS. Whereas, patients older than 65 years or with ECOG PS ≥2 may not benefit more from Bev added to the first-line chemotherapy compared to second-/later-line chemotherapy. PFS of patients received treatment with/without chemotherapy as maintenance therapy showed no significant difference (P=0.354) in >6 courses Bev cohort. As for OS, Bev plus the first-line chemotherapy and number of metastatic sites <3 were independent predictors. The most common adverse effects (AE) were leukopenia, neutropenia, hypertension, and proteinuria. Twenty patients suffered from AE ≥ Grade 3.
conclusionsBev, in combination with the front-line chemotherapy, is proven beneficial for survival well-tolerated.
