Lumen-apposing metal stent for peripancreatic fluid collection contributes to early improvement of nutritional status: A multicenter retrospective study (YCR-P001).

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
Acute pancreatitis causes malnutrition due to severe systemic inflammatory response and organ failure and is associated with increased susceptibility to severe infections and complications such as peripancreatic fluid collection (PFC). PFC is treated using endoscopic ultrasound-guided transluminal drainage (EUS-TD). Lumen-apposing metal stents (LAMSs) have high drainage efficiency and are useful; however, their impact on improving nutritional status and long-term prognosis is unclear. We aimed to evaluate the clinical outcomes and nutritional status after LAMS versus plastic stent (PS) in patients with PFC. This multicenter retrospective study included 59 patients who underwent EUS-TD (18 LAMS and 41 PS) for PFC between December 2018 and March 2023. Nutritional indices (prognostic nutritional index [PNI] and modified controlling nutritional status [M-CONUT]) were evaluated using blood tests 2, 4, and 8 weeks postoperatively, and compared using analysis of covariance, with pretreatment values as covariates. Endoscopic procedure time (21.0 vs 48.0 min; P <.001) and time to diet initiation (3.0 vs 5.0 days; P = .04) were significantly shorter in the LAMS group. There were no differences in the clinical success rate (88.9 vs 85.4%; P >.99), number of procedures (2.0 vs 2.0; P = .68), time to discharge after the procedure (28.5 vs 36.0 days; P = .19), adverse events (16.7 vs 14.6%; P >.99), or recurrence rate (16.7 vs 17.1%; P >.99). Post-procedure PNI (2 weeks: 4.5 vs -0.1; P = .09, 4 weeks: 7.2 vs 0.7; P = .03, 8 weeks: 11.0 vs 5.1; P = .05) and M-CONUT (2 weeks: -1.7 vs 0.5; P = .03, 4 weeks: -2.2 vs 0.4; P = .03, 8 weeks: -3.5 vs -1.1; P = .03) showed better improvement in the LAMS group. LAMS group show earlier improvement of nutrition status than PS group in this study.
