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

Introduction: Despite an increase in the demand for surgical treatment of elderly patients with degenerative spinal disorders, little is known about mortality following spinal surgery in this population. This study aims to identify the incidence and causes of in-hospital mortality in elderly patients after elective spine surgery. Methods: We extracted the data of patients aged ≥65 years who underwent elective spine surgery between December 12, 2016, and May 31, 2022, from our prospective multicenter cohort. The primary outcome was the in-hospital mortality rate. Univariate analysis was conducted to identify potential risk factors for postoperative mortality. The detailed clinical course of patients who died was retrospectively investigated using medical records. Results: A total of 10,976 eligible patients (5,976 males and 5,000 females), with a mean age of 75.5 years, were identified. There were eight in-hospital deaths (0.07%). Univariate analyses showed that the eight patients were significantly older (82.1 years vs. 75.5 years, P=0.008), were more frequently hemodialysis-dependent (50.0% vs. 2.9%, P<0.001), and had a higher proportion of cases with cervical surgery (62.5% vs. 17.0%, P<0.001) and preoperative American Society of Anesthesiologists Physical Status ≥3 (87.5% vs. 14.6%, P<0.001). Death occurred at a median of 24.5 days postoperatively. The causes of in-hospital death were as follows: gastrointestinal diseases in five cases (ischemic colitis in three cases, panperitonitis in one, and intestinal perforation in one), sepsis due to unknown causes in two, and lethal arrhythmia in one. The initial symptoms preceding the lethal clinical course were mainly common gastrointestinal symptoms, such as abdominal pain, anorexia, diarrhea, and vomiting. Conclusions: The main cause of in-hospital mortality was gastrointestinal disease. Surgeons should be aware that common gastrointestinal symptoms can be the initial symptoms of a subsequent lethal clinical course in elderly patients.
