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

The COVID-19 pandemic disrupted surgical care delivery, yet the extent to which shifts from inpatient to outpatient settings have persisted remains unclear. Using medical claims data from Independence Blue Cross (2018-2022), we examined changes in surgery settings across 102 procedures before the pandemic and during the 2 years following the suspension of elective surgeries. After 2 years, inpatient volumes decreased for 9 of the 20 most common pre-pandemic inpatient procedures, with corresponding increases in outpatient utilization. Hip and knee replacements experienced the most pronounced shifts, with inpatient shares falling by more than 40 percentage points. Patients from lower-income census tracts saw greater declines in overall procedure volumes (-6.0%) compared to those from higher-income areas (+5.2%). Total allowed amounts decreased for procedures with outpatient migration, while out-of-pocket costs remained stable. These findings suggest durable, post-pandemic shifts in surgical care delivery patterns, with potential implications for access, costs, and equity.
