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

backgroundPrognoses for treatment of middle and lower rectal cancer remain unclear because anatomical and complex surgical procedures specifically influence long-term outcomes. This study analyzes the long-term outcomes of laparoscopic versus open resection for middle and lower rectal cancer.

methodsPatients (laparoscopic, n = 113; open, n = 123) who underwent curative resection for middle and lower rectal cancer from 2000 to 2005 participated in the study. All operations were performed by the same surgical team with extensive experience in laparoscopic and open procedures. The mean follow-up time of all patients was 74.8 months.

resultsNo statistical differences in local recurrence rate (9.1% vs. 6.4%; log-rank = 0.432; p = 0.511) and in distant recurrence rate (19.7% vs. 15.5%; log-rank = 0.505; p = 0.477) between laparoscopic and open groups were observed within 5 years. The 5-year overall survival rates of the laparoscopic and open groups were 77.9 and 78.9%, respectively; no significant statistical difference was observed between them (log-rank = 0.012; p = 0.913). The 5-year survival rates between groups were not different between stages: stage I (91.7% vs. 92.0%; p = 0.950), stage II (82.8% vs. 79.4%; p = 0.643), and stage III (66.7% vs. 70.3%; p = 0.850). However, significant statistical differences between different stages were observed (log-rank = 11.156; p = 0.004).

conclusionLaparoscopic and open surgery for middle and lower rectal cancer offer similar long-term outcomes. The continued use of laparoscopic surgery in these patients can be supported.
