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

backgroundA time interval between diagnosis and surgery for gastric cancer is necessary, although its impact on survival remains controversial. We evaluated the impact of preoperative time interval on survival in gastric cancer patients.

methodsWe enrolled 332 patients who underwent curative gastrectomy for clinical stage (cStage) I-III gastric cancer between 2012 and 2015. We separately analyzed early- (cStage I) and advanced-stage (cStages II and III) patients. Early-stage patients were divided according to preoperative time interval: short (≤ 42 days) and long (> 42 days) groups. Advanced-stage patients were also divided into short (≤ 21 days) and long (> 21 days) groups. We compared the survival between the short and long groups in early- and advanced-stage patients.

resultsThe median preoperative time interval was 29 days, and no significant differences were found in patient characteristics between the short and long groups in early- and advanced-stage patients. In early-stage patients, the 5-year survival rates of the short and long groups were 86.5% and 88.4%, respectively (P = 0.917). In advanced-stage patients, the 5-year survival rates were 72.1% and 70.0%, respectively (P = 0.552). In multivariate analysis, a longer time interval was not selected as an independent prognostic factor in early- and advanced-stage patients.

conclusionsIn this study, survival difference was not found based upon preoperative time interval. The results do not affirm the delay of treatment without reason, however, imperative extension of preoperative time interval may be justified from the standpoint of long-term survival.
