A visualization analysis of research hotspots and trends in enhanced recovery after surgery (ERAS) for elderly patients based on web of science and scopus.
Article in Journal of cardiothoracic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimsTo analyze the research landscape and thematic evolution of enhanced recovery after surgery (ERAS) in elderly patients from 2009 to 2025 using bibliometric methods.
methodsPublications were retrieved from the Web of Science Core Collection and Scopus databases, limited to English articles and reviews. CiteSpace and VOSviewer were used to analyze annual publication trends, international and institutional collaboration networks, keyword co-occurrence, clustering, and burst detection.
resultsA total of 773 publications were included. Annual publication output increased markedly after 2017. China (183 publications, 23.7%) and the United States (152 publications, 19.7%) were the leading contributors. Keyword clustering identified nine major thematic clusters (Q = 0.4617,S = 0.7527),with "lung neoplasms" and "esophagus resection" emerging as independent clusters. A sub-analysis revealed that 37 publications (4.8%) specifically addressed thoracic surgery, indicating that thoracic ERAS represents an emerging but still underdeveloped subfield within the overall ERAS research landscape. Among the top 20 high-frequency keywords, "aged" (519 occurrences, 67.1%) and "enhanced recovery after surgery" (504 occurrences, 65.2%) were the most prominent. Burst detection revealed 25 keywords with significant citation surges. Recent high-intensity bursts included "functional status" (strength = 7.18), "preoperative exercise" (strength = 6.28), and "physiotherapy" (strength = 5.38), indicating a shift toward functional recovery and prehabilitation. Major research themes focused on frail older populations, colorectal and oncologic surgical applications, perioperative analgesia, and prehabilitation strategies. Temporal overlay and burst analyses indicated sustained prominence of terms such as "functional status", "frailty", and "preoperative exercise".
conclusionsResearch on ERAS in elderly patients has evolved into a multi-thematic knowledge structure with an increasing emphasis on functional outcomes and personalized perioperative management.
