Hiatoplasty for Intrathoracic Gastric Migration Associated with One Anastomosis Gastric Bypass (OAGB).
Article in Obesity surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis 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
purposeThe standard of surgical correction of post-bariatric intrathoracic gastric migration (ITGM) is hiatal hernia repair, but little is known about its efficacy in patients with one anastomosis gastric bypass (OAGB). We present our experience.
methodsThis retrospective cohort study includes all patients with OAGB who had undergone hiatal hernia repair from 2014 to 2019. The primary outcome was recurrence of ITGM as diagnosed by computed tomography and gastroscopy.
resultsA total of 63 patients underwent hiatal hernia repair 2-54 months (median 13) after primary OAGB (40 patients) or concurrent with revisional OAGB after prior sleeve gastrectomy (23 patients). ITGM recurred in 48% of patients with hiatal repair after primary OAGB and in 91% of patients with concomitant hiatal repair. Recurrences were diagnosed after a median interval of 9 and 8.5 months, respectively. Thirty-six patients (57% of total number) required a revision, and a re-recurrence of ITGM was detected in 15 patients. The Cox regression analysis of all hiatal repairs showed that two variables significantly influenced the likelihood of ITGM recurrence: the length of the migrated pouch (hazard ratio 1.32; p = 0.016) and the type of repair. Combining hiatoplasty with ligamentum teres augmentation (LTA) and conversion to Roux-en-Y gastric bypass (RYGB) lowered the probability of ITGM recurrence (compared with stand-alone hiatoplasty; hazard ratio 0.21, p = 0.029).
conclusionThe outcome of hiatal repair in patients with OAGB is unsatisfactory. Stand-alone hiatoplasty is particularly ineffective. The combination of hiatoplasty with LTA and conversion to RYGB improves the early results, but the long-term durability needs to be tested.
