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

backgroundWe reported favorable short-term results of laparoscopic surgery in a randomized study comparing open and laparoscopic surgery for elderly patients with colorectal cancer (CRC). The purpose of this study is to clarify the long-term outcomes of the laparoscopic surgery for elderly patients with CRC.

methodsThe inclusion criteria were ≥ 75 years, adenocarcinoma, ≤ T4a, M0 and elective surgery. The patients were randomly allocated to open or laparoscopic surgery according to the tumor location. The survival rates, recurrence and reasons for death were compared.

resultOne hundred patients (right colon 43, left colon 28, rectum 29) were included in each group. Eight patients who underwent open surgery and 2 patients who underwent laparoscopic surgery were excluded from the analysis because of metastatic diseases and other malignancies found during the operations. One hundred ninety patients (98 open, 98 laparoscopic) were analyzed. There was no difference in the backgrounds excluding more patients with vascular invasion in the laparoscopic rectal cancer. There were no differences in the 5-year overall survival rate (open vs. laparoscopic; 78.9% vs. 82.1%, p = 0.638), 5-year disease-free survival rate (70.5% vs. 62.8%, p = 0.276), 5-year recurrence-free survival rate (76.1% vs. 72.1%, p = 0.419), or 5-year cancer-specific survival rate (86.1% vs. 80.5%, p = 0.208). No differences in survival were detected in the analyses of stage and tumor location. There was no significant difference in the overall recurrence rate or recurrence site. However, distant lymph node metastases and local recurrences were more common after laparoscopic surgery than after open surgery. There was no difference in the cause of death. More than half of the patients died from other diseases in both groups (57.9% vs. 52.6%, p = 0.765).

conclusionLaparoscopic surgery showed similar long-term results compared to open surgery in elderly patients with CRC. Laparoscopic surgery is an effective surgical procedure for elderly patients with CRC.
