Relationship between surgical difficulty and postoperative complications of hand-assisted laparoscopic living donor nephrectomy and establishment of prediction model.

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
backgroundFew studies have systematically explored the factors influencing the difficulty of hand-assisted laparoscopic living donor nephrectomy. To investigate the relationship between the difficulty of hand-assisted laparoscopic living donor nephrectomy and postoperative complications of the donor as well as the recipient, and then build a model for predicting the difficulty of surgery.
methodsIn this study, 60 patients who underwent hand-assisted laparoscopic living donor nephrectomy by the same surgeon from September 2022 to March 2024 were included as the modeling group. 20 patients operated on by another surgeon served as the external validation group. The subjective score (1-3 points) of surgical difficulty was used as the quantitative index of surgical difficulty. Pearson and Spearman correlation tests were used to explore the correlation between preoperative data and surgical difficulty scores of kidney donors, and finally built a prediction model through multiple linear regression analysis.
resultsWith the increase in the difficulty of operation, both donors and recipients' complications were increased. Linear regression analysis showed that only the number of renal arteries, visceral fat thickness and MAP score were independent risk factors for the difficulty of hand-assisted laparoscopic living donor nephrectomy. The prediction equation is as follows: Difficulty score = 0.584*Number of renal arteries + 0.731*MAP score + 0.110*visceral fat thickness.
conclusionsDonors with higher surgical difficulty are more likely to have serious complications after surgery as well as the recipient. We also established a reliable prediction model for the difficulty of hand-assisted laparoscopic donor nephrectomy.
