Contemporary National Inpatient Trends in appendectomy utilization and operative approach in the United States, 2016-2022.
Article in Surgery open science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Contemporary national data on inpatient appendectomy practice remain limited. We evaluated recent trends in appendectomy utilization and operative approach among patients hospitalized with appendicitis and examined patient- and hospital-level factors associated with operative management and inpatient outcomes. Methods: We performed a retrospective cross-sectional study of the National Inpatient Sample from 2016 to 2022. Hospitalized patients with appendectomy procedures were identified using ICD-10 codes. Operative approach was categorized as open, laparoscopic, or robotic. Weighted analyses and multivariable regression evaluated utilization, approach, length of stay, and adverse discharge. Results: Among 1,035,444 appendicitis hospitalizations, appendectomy utilization declined from 88.8% in 2016 to 82.2% in 2022 ( Conclusions: Appendectomy utilization declined while laparoscopy remained dominant, open surgery decreased, and robotic use increased but remained uncommon. These findings provide a national descriptive framework for future clinically granular studies of appendicitis management.
