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

objectiveTo evaluate whether increased body mass index (BMI), age, or frailty influence vestibular schwannoma (VS) short-term surgical morbidity.

methodsThe 2005-2017 National Surgical Quality Improvement Program database was queried for patients with VS undergoing surgical resection. Age was stratified according to age <50, 50-64, and ≥65, while BMI was stratified based on a threshold of 30. Frailty score (0-5) was indicated based on functional status, diabetes, chronic obstructive pulmonary disease, congestive heart failure, and hypertension.

resultsA total of 1405 patients were included consisting of 56.7 % females with a mean age of 50.7 ± 13.8 years and mean BMI of 29.4 ± 6.6. Patients <50 (n = 604), 50-64 (n = 578), and ≥65 (n = 223), had different duration of surgery (428 ± 173 vs. 392 ± 149 vs. 387 ± 154 min; p < 0.001) and 30-day mortality rates (0.7 % vs. 0% vs. 1.8 %; p = 0.01). However, post-operative length of stay (LOS) (p = 0.16), readmission (p = 0.08), reoperation (p = 0.54), and complication rates were similar. Post-operative myocardial infarction (p = 0.03) and wound infection (p = 0.02) were more commonly observed in the obese cohort (BMI≥30) but readmission (p = 0.18), reoperation (p = 0.44), and complication rates were similar to those with BMI<30. Severely obese patients (BMI≥35) also had higher rates of deep vein thrombosis (p = 0.004). Frailty score 0 (n=921), 1 (n=375), and 2-4 (n=109) was associated with LOS (4.7±3.5 vs. 5.3 ± 4.1 vs. 6.7 ± 6.6 days, p < 0.001) and prolonged intubation rates (1.0 % vs. 2.4 % vs. 3.7 %; p = 0.03).

conclusionsIncreased age, BMI, and frailty among VS patients were associated with different post-operative complication rates, operation time, or LOS. Knowledge of these can optimize care for at-risk patients.
