Outcomes of anterior myotomy versus posterior myotomy during POEM: a randomized pilot study.
Article in Endoscopy international open, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 32 papers, 5 of them syntheses that pooled 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.
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 AND STUDY
aimsPeroral endoscopic myotomy (POEM) can be performed via an anterior or posterior approach, depending on the operator's preference. Data are lacking on comparative outcomes of both approaches. PATIENTS AND
methodsThis is a pilot randomized study comparing endoscopic anterior and posterior myotomy during POEM in patients with Achalasia cardia (AC). Patients were randomized into 2 groups (n = 30 in each group); anterior myotomy group (AG) and posterior myotomy group (PG) and were followed at 1, 3 and 6 months after POEM.
resultsTechnical success was achieved in 100 % of cases in both groups and total operative time was comparable (AG - 65 ± 17.65 minutes versus PG - 61.2 ± 16.67;
conclusionAnterior and posterior approaches to POEM seem to have equal efficacy. However, the occurrence of mucosotomies was higher in the anterior myotomy group and acid exposure was higher with the posterior myotomy approach during POEM.
