Utilising systematic reviews to assess potential overtreatment and claim for better evidence-based research: an analysis of anticancer drugs versus supportive care in advanced esophageal cancer.
Article in Systematic reviews, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundHighlighting the identified gaps in evidence-based research concerning advanced esophageal cancer (EC) treatment and care, this review evaluates the efficacy and safety of anticancer drugs compared to supportive care for advanced EC patients, aiming to assess the appropriateness of usual treatments and identify the gaps that need to be filled with primary research.
methodsWe searched (May 2022) MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), Epistemonikos, and trial registries (ClinicalTrials.gov and PROSPERO) for randomised controlled trials (RCTs) comparing anticancer drugs (chemotherapy, immunotherapy, or biological/targeted therapy) with supportive care in advanced EC. The results were summarised using GRADE summary of finding tables.
resultsWe included 15 RCTs. Most studies did not have a special focus on EC, did not detail the treatment lines in all patients, and did not evaluate all outcomes. Anticancer drugs may result in a slight increase in overall survival (OS) (HR 0.78; 95% CI 0.71, 0.86; MD 0.83 months) and better progression-free survival (PFS) (HR 0.56 95% CI 0.49, 0.64, MD 0.68 months), but also may increase toxicity (RR 1.37; 95% CI 1.13, 1.65), without a significant improvement in quality of life. The certainty of evidence was low or very low due to indirectness of results and lack of specific focus on EC in some studies.
conclusionRCTs on advanced EC lack specificity, detailed treatment line information, and evaluation of all relevant outcomes. Moreover, when they find any benefit, this is negligible. Therefore, the certainty to justify anticancer drug treatments instead of supportive care in advanced EC is low or very low, and this information should be actively shared with affected patients. More and better RCTs should be conducted to assess whether any old or new proposed treatment for advanced EC patients provides a better balance of benefits and harms than the supportive care.
