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
Debate regarding the premature aging of knee joints in acquired immune deficiency syndrome (AIDS) patients has remained contentious, with conjectures pointing towards its correlation with distinct antiviral regimes. Protease inhibitors (PIs) stand as a prominent class of antiviral agents frequently utilized in AIDS management and have been significantly linked to premature senescence. This study aimed to investigate whether PI-containing regimens would accelerate osteoarthritis (OA) development and explore the molecular mechanisms underlying this association. A retrospective cohort of 151 HIV-infected individuals, categorized into PI and non-PI groups, was established. Patients in PI group exhibited lower KOOS and a higher prevalence of radiological knee OA than those in non-PI group. Additionally, 25 anti-HIV drugs were screened and among all antiviral drugs, lopinavir had the most detrimental impact on cartilage anabolism, accelerating cartilage senescence and promoting mouse OA development. Mechanistically, lopinavir accelerated cellular senescence by inhibiting Zmpste24 and interfering nuclear membrane stability, which leads to decreased binding between nuclear membrane-binding protein Usp7 and Mdm2 and activates Usp7/Mdm2/p53 pathway. Zmpste24 overexpression reduces OA severity in mice. These findings suggest that PI-containing regimens accelerate cartilage senescence and OA development through Zmpste24 inhibition, which provides new insights into the selection of HIV regimens.
