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
purposeLumbar spinal fusion (LSF) represents a primary surgical approach for treating degenerative lumbar diseases and spinal instability in elderly patients. However, the impact of ERAS protocols in elderly patients undergoing LSF remains unknown. This article aims to summarize the effectiveness and safety of ERAS protocols in elderly patients undergoing LSF, thereby providing evidence-based guidance for perioperative management of this population.
methodsA search was performed across multiple databases, including PubMed, Embase, Cochrane Library, Web of Science, Preprint Platforms (MedRxiv), and Clinical Trial database, to identify eligible studies. Retrospective studies and randomized controlled trials that compared the clinical utility of ERAS with conventional pathways in elderly patients (≥ 65years) undergoing LSF were included. The retrieved literature underwent Meta-analysis R software. Trial sequential analyses were conducted for outcomes reported in at least five studies, using the Trial Sequential Analysis Software.
resultsThe meta-analysis incorporated seventeen eligible studies. Compared with conventional perioperative care, ERAS protocols showed significant benefits across multiple outcomes: reduced length of stay(LOS) (mean difference: -2.29 days; 95%CI: -2.84 to -1.74; I² = 72.7%), decreased intraoperative blood loss (mean difference: -46.2 mL; 95%CI: -73.44 to -19.00; I² = 72.1%), and earlier ambulation (mean difference: -1.53 days; 95% CI: -2.300 to -0.753; I² = 91.7%). The protocol also significantly lowered risks of postoperative complications (OR = 0.44; 95%CI: 0.364 to 0.528; I² = 0%), postoperative nausea and vomiting(PONV) (OR = 0.50; 95%CI: 0.340 to 0.747; I² = 0%), and hospital readmission (OR = 0.66; 95%CI: 0.471 to 0.936; I² = 2.8%).
conclusionThe application of the ERAS protocol in elderly patients undergoing LSF was associated with favorable clinical outcomes, including shorter LOS, lower incidence of postoperative complications, reduced risk of PONV, and decreased readmission rates.
