Pancreas-left gastric artery angle predicts difficulty of suprapancreatic lymph node dissection in gastrectomy for gastric cancer: a cross-sectional study.

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
purposeSuprapancreatic lymph node dissection is one of the most challenging procedures performed in the treatment of gastric cancer. This study aimed to investigate whether the pancreas-left gastric artery angle (PLA) can be used to predict the difficulty of the procedure.
methodsThis was a single-center cross-sectional study. Before gastrectomy, the patients were classified according to the size of the PLA into the small PLA (s-PLA; < 30°) and large PLA (l-PLA; ≥ 30°) groups in a surgeon-blinded manner. After gastrectomy, a surgeon evaluated suprapancreatic lymph node dissection as hard, normal, or easy to perform.
resultsSeventy-three patients were enrolled in the study. Surgeons evaluated lymph node dissection as hard in 43.8 and 8.7% of patients in the s-PLA and l-PLA groups, respectively (p = 0.002). The time taken for suprapancreatic lymph node dissection was also significantly longer in the s-PLA group than in the l-PLA group (p = 0.040). In patients who underwent laparoscopic gastrectomy, the time for node dissection in the s-PLA group was also significantly longer than that in the s-PLA group (p = 0.021), while there was no difference in those who underwent robotic surgery (p = 0.815).
conclusionPLA is useful for predicting the degree of difficulty of suprapancreatic lymph node dissection during gastrectomy for gastric cancer.
