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

Background: Stiffness after knee arthroplasty is commonly treated with manipulation under anesthesia (MUA). Previously identified predictors of MUA include younger age, Black race, low body mass index, diabetes, tobacco use, and prior nonarthroplasty knee surgery. Whether these factors persist in a healthcare system with minimal financial barriers remains unclear. We evaluated rates and predictors of MUA in the U.S. Military Health System (MHS). Methods: This retrospective cohort study queried the MHS Data Repository for patients undergoing primary total knee arthroplasty, revision total knee arthroplasty (rTKA), or unicompartmental knee arthroplasty (UKA) from 2016 to 2022 using Current Procedural Terminology. Minimum follow-up was 6 months. Logistic regression evaluated associations between patient factors and MUA. Results: A total of 8223 knee arthroplasties were identified in 7164 patients. Mean age was 62 ± 9 years; active-duty patients (n = 502) averaged 48 ± 7 years. MUA rates were 4.6% after TKA (315/6833), 2.1% after rTKA (19/885), and 1.4% after UKA (7/505). Protective factors included older age (odds ratio [OR] 0.96/year, Conclusions: Previously identified risk factors, including younger age, Black race, diabetes, and prior knee surgery, remained associated with MUA within the MHS. Active-duty status was not associated with increased MUA risk.
