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

purposeThe purpose of this study was to systematically compare the effectiveness and safety of endoscopic discectomy (ED) with open discectomy (OD) for the treatment of symptomatic lumbar disc herniation (LDH).

methodsA highly sensitive search strategy was used to identify all published randomized controlled trials up to August 2014. A criteria list taken from Koes et al. was used to evaluate the risk of bias of the included studies. The five questions that were recommended by the Cochrane Back Review Group were used to evaluate the clinical relevance. Cochrane methodology was used for the results of this meta-analysis.

resultsNine relevant RCTs involving 1,092 patients were identified. Compared with OD, ED results in slightly better clinical outcomes which were evaluated by the Macnab criteria without clinical significance (ED group: 95.76 %; OD group: 80 %; OR: 3.72, 95 % CI: [0.76, 18.14], P = 0.10), a significantly greater patient satisfaction rate (ED group: 93.21 %; OD group: 86.57 %; OR: 2.19; 95 % CI: [1.09, 4.40]; P = 0.03), lower intraoperative blood loss volume (WMD: -123.71, 95 % CI: [-173.47, -73.95], P < 0.00001), and shorter length of hospital stay (WMD: -Table 2144.45, 95 % CI: [-239.54, -49.37], P = 0.003).

conclusionsFrom the existing outcomes, ED surgery could be viewed as a sufficient and safe supplementation and alternative to standard open discectomy. The cost-effectiveness analyses still remain unproved from the existing data. More independent high-quality RCTs using sufficiently large sample sizes with cost-effectiveness analyses are needed.
