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

BACKGROUND AND

aimsThe colon cancer survival rate is significantly affected by location, stage, and size of the cancer. Polypectomy was shown be as equally effective as surgery in early-stage colon cancer, but there have been no established clinical guidelines in the management of colon cancer based on the size of the polyp or the tumor location. The aim of our study was to assess the early-stage colon cancer-specific survival rate in patients who underwent endoscopic polypectomy versus surgery, based on size and location of tumor in early-stage colon cancer.

methodsThis is a population-based nationwide study in the USA.

resultsOf 13,157 patients, 15.5% underwent endoscopic treatment and 84.5% underwent surgical therapy. For early cancer tumors located in the left colon, polypectomy yielded comparable 5-year survivals to surgery irrespective of size of the tumors. Five-year early cancer-specific survivals were similar for tumors located in the right colon that were < 20 mm in size (94.5 vs 94.3%, p value = 0.94). However, tumors > 20 mm in size that were located in the right colon had better survivals when treated surgically compared to those treated with polypectomy (20-39 mm: 91.8 vs 74.2%; ≥ 40 mm: 92.4 vs 60%, both p values < 0.01). Similar results were obtained on propensity score analysis.

conclusionsPolypectomy was as effective as surgical therapy for small tumors. For larger tumors, surgical therapy is better than polypectomy for right-sided tumors, but both are equally effective for left-sided tumors.
