Impact of Preoperative Ineffective Oesophageal Motility on Postoperative Dysphagia Following Nissen Fundoplication: A Systematic Review and Meta-Analysis.
Review in Cureus, 2025. 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
Nissen fundoplication (NF) is one of the most common anti-reflux surgeries (ARS) performed worldwide for gastro-oesophageal reflux disease (GERD). There is a theoretical belief that ineffective oesophageal motility (IEM) can cause increased postoperative dysphagia (POD) following NF due to weak and failed peristalsis against a 360-degree wrap. There is scarce evidence to support the hypothesis that NF in pre-existing ineffective oesophageal motility causes increased POD. This study aims to identify the impact of preoperative IEM on POD following NF. In this study, based on the PRISMA guidelines, we conducted a systematic search for articles published in PubMed, Scopus, EMBASE, as well as in the Cochrane Library, using the search terms "ineffective oesophageal motility", "motility disorder and fundoplication", "Esophageal hypomotility", "Ineffective esophageal motility and GERD" from the inception of these databases to an end date of September 22, 2025. The study participants included patients who had NF for GERD and who had pre-existing IEM. These patients were compared with NF patients with normal motility or non-IEM patients. The outcome measured was POD following NF. The odds ratio and its 95% confidence interval were calculated using the random-effects model. A sensitivity analysis was performed to assess heterogeneity within the study population. For publication bias funnel plots and risk of bias assessment in randomised controlled trials, the Risk of Bias 2 (RoB) is used. For non-randomised studies, the Newcastle-Ottawa Scale (NOS) score is employed. A total of 10 articles were identified in the search, involving 1473 patients, of whom 1093 had undergone Nissen fundoplication. Among these 1093 patients, 427 had pre-existing IEM. The forest plot in this study suggests that there is no statistical significance in the POD between IEM and non-IEM patients following NF (P = 0.30, Odds ratio = 1.20, overall effect Z = 1.04, df = 5, I
