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

backgroundSeveral studies have confirmed that laparoscopic colorectal surgery (LCS) has superior short-term outcomes when compared to open colorectal surgery. However, the evidence for cost-effectiveness of LCS is less clear.

aimThe aim of this study is to explore the cost-effectiveness of LCS over time since it was first developed in 1991.

methodsSystematic review of the literature was conducted. Electronic databases (PubMed, ScienceDirect and Google Scholar) were searched for studies from 1991 to 2010 using the keywords "laparoscopic, colorectal surgery cost, economic evaluation".

resultsFifteen economic evaluations met the inclusion criteria. The percentage cost difference between open and laparoscopic surgery varied widely between different studies. The general trend when observing all the included economic evaluations is that there is a moderate negative correlation between progression of time and the size of the cost gap between laparoscopic and open surgery (R-value=-0.44). This correlation is even stronger (R-value=-0.64, P=0.046) if the studies are subdivided by the country where the surgery was carried out in. Western healthcare systems, even though they had a heterogeneous set of results (SD=27%), showed a decline in costs of laparoscopic surgery with time.

conclusionFrom the current trends, it is projected that the results of future economic evaluations will unequivocally show that laparoscopic surgery is cheaper than open surgery. The initial higher costs of laparoscopic surgery training may be worth the savings made in the long term if it is practised in settings where postoperative care is expensive.
