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

Post-esophagectomy hiatal hernia (PEHH) is a rare but potentially serious complication of esophagectomy, particularly following minimally invasive approaches. This study aims to evaluate the incidence, risk factors, diagnostic methods, and therapeutic strategies for PEHH through a systematic review and meta-analysis. MEDLINE, Scopus and Cochrane bibliographical databases were systematically searched according to PRISMA guidelines for studies concerning PEHH (last search: 22nd February 2025). A meta-analysis was conducted with pooled odds ratios (ORs) to assess potential risk factors. Thirty-four studies with 837 PEHH cases were included. The overall incidence of PEHH was 4.1%. Minimally invasive esophagectomy (MIE) was associated with an increased risk for PEHH (OR: 5.70, p-value < 0.001). Obesity (BMI > 25 kg/m
