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

introductionPlasma from the second and third weeks after minimally invasive colorectal resection (MICR) has high levels of the proangiogenic proteins VEGF and angiopoietin 2 and also stimulates, in vitro, endothelial cell (EC) proliferation and migration, which are critical to wound and tumor angiogenesis. Soluble vascular cell adhesion molecule-1 (sVCAM-1) stimulates EC chemotaxis and angiogenesis. The impact of MICR on blood levels of sVCAM-1 is unknown. This study's purpose was to determine plasma sVCAM-1 levels after MICR in colorectal cancer (CRC) patients.

methodsBlood samples from 90 patients (26% rectal, 74% colon) were obtained preoperatively, on postoperative days (POD) 1 and 3, and at other points during the next 2 months. The late samples were bundled into 7-day time blocks. sVCAM-1 levels were determined in duplicate via ELISA and reported as ng/ml. Student's t test was used for data analysis (significance, P < 0.008 after Bonferroni correction).

resultsThe mean incision length was 7.3 ± 3.1 cm, and the conversion rate was 3%. Compared with preoperative (PreOp) levels (811.3 ± 233.2), the mean plasma sVCAM-1 level was significantly higher on POD 1 (905.7 ± 292.4, P < 0.001) and POD 3 (977.7 ± 271.8, P < 0.001). Levels remained significantly elevated for the POD 7-13, POD 14-20, POD 21-27, and POD 28-67 time blocks.

conclusionsMICR for CRC is associated with a persistent increase in plasma sVCAM-1 levels during the first month. This sustained increase may promote angiogenesis and stimulate the growth of residual tumor cells early after surgery.
