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

purposeWe evaluated the need for primary tumor resection in patients with colorectal cancer (CRC) and synchronous unresectable metastases who underwent chemotherapy, and identified the associations between the primary tumor characteristics and risk of intestinal obstruction or perforation.

methodsWe retrospectively analyzed the survival and complication rates of patients with synchronous metastatic CRC treated between April 2005 and December 2011.

resultsOf 131 patients, 68 underwent primary tumor resection before chemotherapy, and 63 were treated without resection before chemotherapy. The overall survival (OS) did not significantly differ between the two groups (log-rank P = 0.53). In the resection group, 12 patients (17.6%) developed postoperative complications. In the non-resection group, 16 patients (25.4%) required surgical intervention owing to obstruction or perforation during their treatment. Surgical intervention did not affect the OS. A circumferential tumor was a risk factor for obstruction or perforation of the colorectum in non-resected patients (odds ratio = 11.163; P = 0.006).

conclusionResection of primary tumors before chemotherapy is unnecessary in selected patients with synchronous metastatic colorectal cancer. A circumferential tumor is a risk factor for obstruction or perforation during chemotherapy in cases without primary tumor resection.
