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
backgroundIn situations of osteoarthritis (OA), the therapeutic value of knee arthroscopy is still a topic of discussion that is ongoing. This study aims to produce data about the relevance of arthroscopy and total knee arthroplasty (TKA) in knee OA by assessing the overall rates of arthroscopy and subsequent conversion to TKA over a two-year period in QLD Australia within the time frame between 2008 and 2023.
methodsA retrospective cohort analysis was undertaken at Queensland (QLD) hospitals that underwent arthroscopy and TKA between 2008 and 2023. Research datasets obtained from the Centre for Health Record Linkage (CHeReL) were analyzed using negative binomial regression. An investigation was performed to determine the rates of arthroscopy admissions by year, age group, sex, and hospital system (public versus private). The TKA readmission rates were calculated during a 24-month period.
resultsThe results demonstrate an overall decrease in the frequency of arthroscopies from 2008 to 2022, but total knee arthroplasties (TKA) have increased by 2.79% (95% CI: 2.19 to 3.38). There was a 3.34% reduction in arthroscopy rates at private hospitals and a 0.98% drop at public hospitals (95% CI: -0.26 to 2.23). The largest significant rise in TKA rates was seen in private hospitals. The TKA procedure was performed on 14.48% of patients aged 65 and older within 24 months of knee arthroscopy. After taking sex and age into account, there was a 4.97% reduction in the occurrence of total knee TKA within 24 months following knee arthroscopy (95% CI: -5.55 to -4.40) across the board.
conclusionsWhile the rates of TKA are on the rise, arthroscopies and their conversions to TKA are on the decrease. Possible explanations for the persistent drop in TKA conversion rates include better patient selection, more effective non-operative care, or longer wait times for the operation.
