American society of anesthesiologists grade and association with joint specific outcome, health-related quality of life, readmission and mortality risk after hip and knee arthroplasty.

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
aimsThe aims were to assess whether American Society of Anesthesiologists (ASA) grade influenced improvement in joint-specific outcomes (JSO), health-related quality of life (HRQoL), length of stay (LOS), readmission, or mortality after knee (KA) or total hip arthroplasty (THA).
methodsThis retrospective study was conducted over a 6-year period and included 7644 KA and 7745 THA. Patient demographics, ASA grade, LOS, 30-day readmission and postoperative mortality were recorded from National electronic medical records. Preoperative and 1-year postoperative Oxford knee/hip scores (OKS/OHS), EQ-5D and EQ-VAS scores were obtained from a local arthroplasty register, which had postoperative data for 6272 KA and 6182 THA.
resultsFor both KA and THA cohorts, increasing ASA grade was associated with female gender (p < 0.001), older age (p < 0.001), and worse preoperative Oxford (p < 0.001), EQ-5D (p < 0.001), and EQ-VAS (p < 0.001) scores. Unadjusted improvements in OKS (p = 0.866), EQ-5D (p = 0.574) or EQ-VAS (p = 0.714) were not significantly influenced by ASA grade after KA. In contrast, those with a worse ASA grade had significantly (p < 0.001) greater improvements in the OHS and EQ-5D. A higher ASA grade was associated with an increased risk of readmission (KA p = 0.020, THA p < 0.001). When adjusting for confounding factors ASA grades 3 and 4 were associated with an increased risk of mortality relative to ASA 1 following KA and THA. ASA 3 (KA + 0.9 days, p < 0.001) and 4 (KA + 2.0 days, p < 0.001, THA + 3.0 days p < 0.001) were also independently associated with an increased length of stay relative to grade 1.
conclusionIncreasing ASA grade did not have a clinically meaningful association with improvement in JSO or HRQoL following KA and THA, but was associated with an increased LOS, 30-day readmission and postoperative mortality risks. LEVEL OF EVIDENCE: Retrospective study, Level III.
