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

Changing surgical settings for orthopaedic procedures could drive reductions in operative time and reduce healthcare costs. Time-cost differences were calculated using estimated operating room costs by utilizing the ACS-NSQIP database. Multivariate analyses were generated from propensity-matched cohorts to assess differences between inpatient/outpatient outcomes, and whether surgical length increased risk for complications. Outpatient procedures demonstrated time-cost savings of $1716.06. Generally, inpatient procedures demonstrated increased rates of major/minor complications, reoperation, extended LOS, and unplanned readmission (p < 0.001). Overall, longer operative times increased the risk for postoperative complications (p ≤ 0.001). More elective orthopaedic procedures done on an outpatient basis may result in substantial time-cost savings.
