Preliminary study of surgical audit for overall survival following gastric cancer resection.
Article in Gastric cancer : official journal of the International Gastric Cancer Association and the Japanese Gastric Cancer Association, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
backgroundPrevious studies for surgical audit have focused on short-term outcomes, such as perioperative mortality. There has been no gold standard how to evaluate quality of care for long-term outcomes in surgical oncology. This preliminary study aims to propose a method for surgical audit targeting long-term outcome following gastrectomy for gastric cancer.
methodsWe prospectively investigated a set of variables relating to physiologic conditions, tumor characteristics and operations in patients who underwent gastrectomy for gastric cancer between June 2005 and July 2008 in 18 referral hospitals in Japan. Overall survival (OS) is the endpoint. Cox hazard regression analysis was used to generate a model to predict OS. The calibration and discrimination power of the model were assessed using the Hosmer-Lemeshow (H-L) test and area under the receiver-operating characteristic curve (AUC), respectively. The ratio of observed-to-estimated 5-year OS rates (OE ratio) was defined as a measure of quality.
resultsAmong 762 patients analyzed, 697 (91%) completed the 5-year follow-up. The constructed model for OS exhibited a good discrimination power (AUC, 95% confidence interval 0.89, 0.86-0.91), which was significantly better than that for the UICC stage (0.81, 0.77-0.84). This model also demonstrated a good calibration power (H-L: χ(2) = 27.2, df = 8, P = 0.77). The OE ratios among the participating hospitals revealed no significant variation between 0.74 and 1.1.
conclusionsThe current study suggests the possibility of surgical audit for postoperative OS in gastric cancer. Further studies including high-volume centers will be necessary to validate this idea.
