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

backgroundCentralization of specialist surgical services can improve patient outcomes. The aim of this cohort study was to compare liver resection rates and survival in patients with primary colorectal cancer and synchronous metastases limited to the liver diagnosed at hepatobiliary surgical units (hubs) with those diagnosed at hospital Trusts without hepatobiliary services (spokes).

methodsThe study included patients from the National Bowel Cancer Audit diagnosed with primary colorectal cancer between 1 April 2010 and 31 March 2014 who underwent colorectal cancer resection in the English National Health Service. Patients were linked to Hospital Episode Statistics data to identify those with liver metastases and those who underwent liver resection. Multivariable random-effects logistic regression was used to estimate the odds ratio of liver resection by presence of specialist hepatobiliary services on site. Survival curves were estimated using the Kaplan-Meier method.

resultsOf 4547 patients, 1956 (43·0 per cent) underwent liver resection. The 1081 patients diagnosed at hubs were more likely to undergo liver resection (adjusted odds ratio 1·52, 95 per cent c.i. 1·20 to 1·91). Patients diagnosed at hubs had better median survival (30·6 months compared with 25·3 months for spokes; adjusted hazard ratio 0·83, 0·75 to 0·91). There was no difference in survival between hubs and spokes when the analysis was restricted to patients who had liver resection (P = 0·620) or those who did not undergo liver resection (P = 0·749).

conclusionPatients with colorectal cancer and synchronous metastases limited to the liver who are diagnosed at hospital Trusts with a hepatobiliary team on site are more likely to undergo liver resection and have better survival.
