1 · What the graph read from it

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.

2 · The registry

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

Reoperation is a serious adverse event after laparoscopic pancreatoduodenectomy (LPD). This study aims to identify risk factors of reoperation after LPD and evaluated the impact of the learning curve. Patients undergoing LPD from February 2014 to May 2024 were retrospectively reviewed. A logistic regression analysis was performed to identify predictors of unplanned reoperations within 90 days. Learning curve analysis was performed to compare surgical outcomes across different stages. Of the 445 patients undergoing LPD, 33 (7.4%) required unplanned reoperation within 90 days. Univariable and multivariable analysis identified prolonged operative time (OR 1.325, 95% CI 1.060-1.670; p = 0.015), intraoperative blood transfusion (OR 2.764, 95% CI 1.049-6.717; p = 0.030), and non-pancreatic ductal adenocarcinoma (PDAC) pathology (OR 2.432, 95%CI 1.120-5.461; p = 0.027) as independent risk factors, while pylorus preservation was protective (OR 0.362, 95%CI 0.151-0.895; p = 0.024) for reoperation after LPD. Learning curve analysis revealed reoperation rates significantly decreased from stage I (20.0%) to the later learning stages (Stage II: 20.0% vs. 5.0%, p = 0.014; Stage III: 20.0% vs. 6.4%, p = 0.006). Prolonged operative time, transfusion, and non-PDAC pathology increased reoperation risk, whereas pylorus preservation was protective. Most reoperations occurred early in the learning curve, with rates decreasing as surgical proficiency improved.
