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

introductionThere are only few studies about the outcomes of peroral endoscopic myotomy (POEM) for type III achalasia in a relatively large population to date. The purpose of this study was to explore the long-term efficacy of POEM for patients with type III achalasia.

methodsThere were a total of 32 consecutive patients with type III achalasia undergoing POEM in our hospital from July 2012 to October 2014. Clinical date of general characteristics, procedure-related parameters and adverse events, symptom relief, and the high-resolution manometry outcomes before and during the periodic follow-up were retrospectively collected and analyzed.

resultsAll of the 32 patients underwent POEM successfully with a median operation time of 34.9 min (range 17.9-88.6 min). No serious complications related to POEM were encountered. Treatment success was achieved in 90.6% cases during a median follow-up period of 27.0 months (range 24-51 months). The mean pretreatment and post-treatment Eckardt scores were 7.2 and 1.4, respectively (P < 0.001), and mean LES pressure also decreased from a mean of 39.2 to 19.0 mmHg after the procedure (P < 0.001). Both of the gas-related complication and clinical reflux complication rates were 18.8%.

conclusionOur results confirm that POEM for type III achalasia of Chicago Classification is effective with a long-term symptom relief in 90.6% cases. But a further, prospective study is needed to evaluate whether POEM outcome could be correlated with manometric subtypes according to Chicago Classification.
