Addition of Bevacizumab to First-Line Palliative Chemotherapy in Patients with Metastatic Small Bowel Adenocarcinoma: A Population-Based Study.
Article in Targeted oncology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
backgroundData about the use and effectiveness of targeted therapy in metastatic small bowel adenocarcinoma (SBA) are scarce.
objectiveThe aim of this population-based study was to obtain insights into the use and effectiveness of targeted therapy in patients with synchronous metastases of SBA. PATIENTS AND
methodsData were retrieved from the Netherlands Cancer Registry. Patients treated with palliative chemotherapy and/or targeted therapy for synchronous metastatic SBA between 2007 and 2016 were included (n = 187). Differences in treatment and the subsequent effects on overall survival (OS) were evaluated.
resultsIn first-line treatment, 25 patients (13%) received additional targeted therapy, exclusively bevacizumab, and mostly in combination with CAPOX/FOLFOX (n = 24). A primary ileal tumour was predictive for receiving bevacizumab in first-line treatment (odds ratio 3.2, 95% confidence interval (CI) 1.06-9.93). Median OS for patients in whom bevacizumab was added to first-line chemotherapy was 9.3 months, compared to 9.1 months with chemotherapy only (p = 0.85). Median OS for patients receiving first-line treatment only was 8.5 months with and 6.4 months without the addition of bevacizumab, respectively (p = 0.54). In multivariable survival analyses, the addition of bevacizumab was no prognostic factor (hazard ratio 1.01, 95% CI 0.65-1.59).
conclusionsBevacizumab was the only prescribed targeted therapy in first-line treatment. Considering the limited number of patients receiving first-line bevacizumab and the unknown reasons to prescribe additional targeted therapy, the corresponding survival rates of patients treated with and without additional bevacizumab in first-line treatment might suggest a limited clinical effect of bevacizumab in addition to first-line palliative chemotherapy on OS. Future research should focus on identifying the subgroup of patients who might benefit from anti-VEGF therapy in metastatic SBA.
