Water intake pancreatic ultrasonography improves pancreatic body and tail visualization: contributing factors revealed by quantitative analysis.

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
purposeTransabdominal pancreatic ultrasound is simple and noninvasive; however, the image quality is often degraded by visceral fat and gastrointestinal gas. Water intake pancreatic ultrasonography (WPUS) may help address this limitation, but quantitative evidence remains limited. We evaluated the effects of WPUS and examined the 10-grade Pancreatic Image Scale (PIS) as a quality control metric.
methodsWe retrospectively reviewed the medical records of 581 patients who underwent WPUS. The PIS (0-9) was recorded before and after water intake, and improvements were analyzed for associations with body mass index (BMI), age, and sex to identify factors influencing pancreatic visualization. We added a reproducibility study in which three gastroenterologists independently re-scored 30 anonymized cases three times.
resultsWPUS improved pancreatic visualization in 82% of cases; the proportion achieving PIS ≥ 6 increased from 17% in pre-water supine scans to 54-71% after WPUS (P < 0.001). Higher BMI was associated with lower baseline PIS (β = - 0.12, P < 0.001). WPUS-related improvement was significantly greater in women than in men (β = 0.99, 95% CI 0.56-1.42, P < 0.001). PIS demonstrated moderate-to-good repeatability (intra-reader ICC 0.80; inter-reader ICC 0.71).
conclusionFactor analysis indicated no sex difference in pre-WPUS pancreatic visualization, but women exhibited greater improvement after water intake. WPUS significantly improved visualization of the pancreatic body and tail, as reproducibly quantified using PIS. These findings support WPUS as a practical tool for routine clinical assessment and as a potential adjunct to early detection strategies for pancreatic disease.
