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

introductionObesity is a known risk factor for postoperative complication after ventral or incisional hernia repair (VIHR). Whether minimally invasive techniques can mitigate this risk for certain patients remains unknown. This study investigates whether MIS approaches offer advantages in reducing any medical or surgical complication after VIHR across clinically meaningful BMI categories.

methodsThis study analyzes data from the Michigan Surgical Quality Collaborative Core Optimization Hernia Registry (MSQC COHR). The registry is a representative, random sample of adult patients from 70 Hospitals across the state of Michigan. This study includes adult patients receiving VIHR between Jan 2020 and September 2023. All elective VIHRs captured in the MSQC database were included in analysis. Univariate statistics were used for cohort summary and multivariate logistic regression was used to estimate the probability of any 30-day postoperative complication while controlling for age, sex, the interaction of BMI and surgical approach, medical comorbidities, hernia size, mesh use, use of component separation, and previous hernia repair.

resultsA total of 11,886 people met the study inclusion criteria. The median (IQR) age was 55.0 (44-65) and 5,111(43.0%) were female. The median (IQR) BMI was 31.7 (27.6-36.3). 5,260(44.3%) cases were performed with an MIS approach and 6,626(55.7%) were performed with an open approach. The adjusted relative risk of experiencing a complication after open repair when compared to MIS repair was 1.34 (95% CI [1.04-1.70], p = .02) in Obesity Class I, 1.62 (95% CI [1.23-2.14], p < .001) in Obesity Class II, and 2.31 (95% CI[1.49-3.56]) for Obesity Class III.

conclusionsMIS repair was associated with improved 30-day outcomes for patients with class I, II, and III obesity, but not for healthy to overweight patients. In clinical scenarios where delay for severely obese patients may be difficult, electing to use an MIS repair may be the optimal strategy to reduce risk of complications.
