Comparison of Ivor Lewis and Sweet esophagectomy for middle and lower esophageal squamous cell carcinoma: A systematic review and pooled analysis.
Article in EClinicalMedicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundLack of robust evidence highlights the important need to address the controversy on the clinical safety and effectiveness between Ivor Lewis versus Sweet procedure for middle and lower esophageal squamous cell carcinoma (ESCC).
methodsSearch results were filtered according to certain criteria and were analyzed in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
findingsThe inter-study heterogeneity was high. Ivor Lewis procedure might be associated with longer operation time (
interpretationThe present study based on retrospective data with high heterogeneity indicated that Ivor Lewis esophagectomy might be associated with increased lymph node yield but longer operation time than Sweet. Prospective studies are warranted to compare the long-term survival of Ivor Lewis esophagectomy versus Sweet for middle and lower ESCC.
