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

In recent years, the use of laparoscopic surgery has been expanded to include radical curative resection. In a previous study, 212 patients with primary colorectal cancer (stages I-III) underwent radical curative resection by hand-assisted laparoscopic surgery (HALS) (n=98) or conventional laparotomy (CL) (n=114) and were compared with respect to 3-year relapse-free survival (3Y-RFS) and 3-year overall survival (3Y-OS). The study included 210/212 patients who were followed up to 5 years, including 96 patients who underwent HALS and 114 treated with CL. The two groups were matched for stage, clinical background, and postoperative management. Patient characteristics were compared and the 5Y-RFS and 5Y-OS were determined. The 5-year follow-up rate was 97.6%. In stage I-III patients, 5Y-RFS and 5Y-OS showed no significant differences between HALS and CL. The patients with stage I disease accounted for 41.7% (40/96) of the patients undergoing HALS, while stage I patients only accounted for 23.7% (27/114) of the patients undergoing CL, and the difference was significant (P=0.005). Stage II patients undergoing CL were older than those treated with HALS (P=0.017). However, there were no differences in the characteristics of stage III patients undergoing HALS or CL. In conclusion, HALS achieved a similar survival to CL in patients with stage I to III colorectal cancer. Compared with CL, HALS was performed more safely and achieved superior cosmetic results.
