A preoperatively predictive difficulty scoring system for laparoscopic spleen-preserving splenic hilar lymph node dissection for gastric cancer: experience from a large-scale single center.
Article in Surgical endoscopy, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
objectivesThe purpose of this study was to evaluate the risk factors that influence the difficulty of performing laparoscopic spleen-preserving splenic hilar lymph node dissection (SHLND) for gastric cancer and to establish a simple and effective scoring system to predict the surgical difficulty preoperatively.
methodsBetween January 2011 and December 2013, we prospectively collected and retrospectively analyzed the medical records of 317 patients with upper- or middle-third gastric cancer who underwent laparoscopic spleen-preserving SHLND. Univariate and multivariate analyses were performed to determine the independent predictors for surgical difficulty based on the operation time during spleen-preserving SHLND. A logistic regression model was used to identify determinant variables and construct a predictive difficulty scoring system.
resultsMultivariate analysis showed that gender, body mass index (BMI), number of splenic lobar arteries (SLAs), and type of SLA were independently predictive factors of operation time. According to these factors, we developed a predictive surgical difficulty scoring system and the difficulty levels are divided into 0, 1, 2, 3, and 4 points or more. Based on the relative risk, we stratified the surgical difficulty into the following three divisions: 0 low difficulty, 1-2 intermediate difficulty, and 3 points or more high difficulty. The patients with long operation time accounted for 19.6, 43.6, and 90.9 % for the three groups, respectively (p < 0.001). The area under the receiver operating characteristic curve for the logistic regression model and the simplified difficulty scoring prediction model was 0.717 and 0.715, respectively.
conclusionsBased on four independent risk factors, including gender, BMI, number of SLAs, and type of SLA, we developed a simple and effective scoring system to predict the difficulty of laparoscopic spleen-preserving SHLND preoperatively. This novel scoring system might aid surgeons with different experience in performing operations at different levels of difficulty.
