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-Critical limb ischemia (CLI) is one of the most severe peripheral artery diseases. Angioplasty and bypass surgery are two major approaches for the treatment of CLI, however, it remains unclear which treatment has better benefit/risk ratio. In this paper, we performed a meta-analysis on the available clinical trials to compare these two approaches in terms of mortality, amputation-free survival, 5-year leg salvage, and freedom from surgical re-intervention. The results of this article will provide evidence based information for clinical treatment of CLI. Method-Randomized clinical trials comparing results between angioplasty and bypass surgery in CLI were identified by searching Pubmed (2000-2014) and EMBASE (2000-2014) using the search terms "angioplasty" or "bypass", "CLI" and "clinical trials". Primary outcome subjected to meta-analysis was amputation (of trial leg) free survival in 5 years. Secondary outcomes were 30-day mortality; mortality, re-interventions and leg salvage in 1, 3 and 5 years. Results-Seven clinical trials were selected for meta-analysis. No significant difference was found in the primary outcome-amputation free survival, between angioplasty and bypass surgery groups. The amputation free survival in 1, 3 and 5 years were 332/498 (66.7%), 169/346 (48.8%) and 21/60 (35%) in angioplasty group, versus 484/749 (64.6%), 250/494 (50.6%) and 46/132 (34.8%), in bypass group, respectively. The 30 days mortality rate was significantly higher in bypass treatment group [79/1304 (6.1%)] than in angioplasty group [30/918 (3.3%) [95% CI 0.55 [0.36, 0.86], P=0.008). However, there was no statistical significance in 1, 3 and 5 years mortality between these two groups. Two clinical trials showed that there was no difference in leg salvage between angioplasty and bypass surgery groups either. In addition, no difference was observed in re-vasculation between the two groups. Conclusion-Angioplasty is non-inferior to bypass surgery in regarding the amputation free survival, re-vasculation, leg amputation and overall mortality. However, angioplasty is safer, simple, and less invasive and less cost procedure. It should be considered as the first choice for feasible CLI patients.
