Real-time imaging-guided visualization facilitates post-pyloric feeding tube placement in critically ill patients: a prospective randomized controlled study.
Trial report in European journal of clinical nutrition, 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
backgroundEarly post-pyloric feeding is critical for improving outcomes in critically ill patients. While guided feeding tube placement has demonstrated superior efficacy to blind insertion, its clinical application remains constrained by technical and operational challenges. The integrated real-time imaging system (IRIS) addresses these limitations by combining continuous lumen visualization with device portability, potentially democratizing precise feeding tube placement. This study evaluated whether IRIS-assisted placement achieved higher efficacy while maintaining equivalent safety compared to traditional blind bedside insertion.
methodsIn this prospective randomized controlled trial, a total of 46 critically ill patients requiring enteral nutrition due to dysphagia or high aspiration risk were randomized to IRIS-guided visualization (VG group) or blind insertion (CG group). One patient was excluded from the analysis because of a major protocol violation. The primary and secondary outcomes were the procedural time and first-attempt success rate, respectively. Safety outcomes included adverse events and hemodynamic stability.
resultsAmong the 45 analyzed patients (VG: 22, CG: 23), the VG group presented a significantly shorter median procedural time (3.19 vs. 22.52 min; 95% CI, -32.23 to -14.22; P < 0.0001) and a higher first-attempt success rate (95.45% vs. 69.57%; odds ratio, 9.19; 95% CI, 1.02-82.41; P = 0.047) than the CG group. Adverse event incidence and hemodynamic stability were comparable between the groups.
conclusionIRIS-guided visualization technology significantly reduces the procedural duration and improves the first-attempt success rate for post-pyloric feeding-tube placement in critically ill patients, while enabling real-time anatomical visualization.
