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
introductionEsophagectomy was considered the first line for advanced sigmoid (aSg) achalasia (esophageal angulation < 90°), while laparoscopic Heller myotomy (LHM) has a lower percentage of success. The pull-down LHM (PD-LHM) technique has emerged as a promising and more effective rescue therapy to avoid esophagectomy for aSg achalasia. However, the long-term functional results of PD-LHM are inconclusive.
objectiveTo compare the outcome of aSg achalasia (< 90°) who underwent the PD-LHM technique with those of non-advanced (naSg) achalasia (≥ 90°) and LHM. PATIENTS AND
methodsThis ambispective nested cohort study evaluated 34 achalasia patients with megaesophagus divided into two groups: (a) aSg (< 90°; n = 20; 59%) PD-LHM treated, and (b) naSg (≥ 90°; n = 14; 41%) LHM treated. The assessments included esophageal angulation and symptom questionnaires. All patients were clinically and manometrically evaluated before and at 1- and 12-month post-surgery intervals. Clinical outcomes focused on achieving esophageal angulation ≥ 90° and an Eckardt score < 3.
results65% of patients were men, and 65% had achalasia type I. The mean esophageal angulation in aSg was 79.6 ± 8.8°, and in naSg was 116.3 ± 16.3°. aSg improved to 99.5 ± 15.2°, and 17/20 patients (85%) shifted to the naSg group. aSg significantly improved in Eckard symptom score at 1 month (1.2 ± 1.3) vs. preoperative score (8.9 ± 1.6). The three aSg patients who experienced PD-LHM failure were male, type I achalasia, had higher preoperative IRP and LES pressure, were older, and had longer disease duration vs. success. A good clinical and manometric outcome was obtained in 85% of aSg.
conclusionOur findings suggest that PD-LHM is an effective treatment for aSg with a success rate of 85%.
