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

backgroundPrevious research has demonstrated the therapeutic potential of aerobic exercise in alleviating symptoms of knee osteoarthritis (KOA). Nevertheless, comparative evidence regarding the relative effectiveness of different exercise modalities remains inconclusive, and the optimal exercise protocol continues to be debated. To address this knowledge gap, we performed a systematic network meta-analysis to compare and rank the clinical efficacy of various aerobic exercise regimens for managing KOA.

methodsA systematic literature search was conducted across five electronic databases (PubMed, Cochrane Library, Web of Science, Embase, and Scopus) from database inception through June 2024. Eligible studies included randomized controlled trials (RCTs) evaluating aerobic exercise interventions for KOA management. Two investigators independently performed study selection using predefined inclusion criteria, with discrepancies resolved through consensus or third-party adjudication. Data extraction encompassed demographic characteristics, intervention protocols, and outcome measures. Methodological quality was assessed using the Cochrane Risk of Bias Tool 2.0. Statistical analyses were performed using Stata 17.0 (Network Meta-Analysis package) under a frequentist framework, with treatment effects estimated through surface under the cumulative ranking curve (SUCRA) probabilities.

resultsThe network meta-analysis included 67 randomized controlled trials comprising 4,944 patients with knee osteoarthritis (KOA), assessing 10 aerobic exercise interventions: walking (WK), weight-loss walking (LK), retro walking (RW), cycling (CY), aquatic training (AT), yoga (YG), Tai Chi (TC), Baduanjin (BD), Wuqinxi (WQ), and Pilates (PT). Surface under the cumulative ranking curve (SUCRA) probability analyses yielded the following results: Pilates (PT) demonstrated the highest probability of being optimal for WOMAC pain score (SUCRA = 0.8%), WOMAC stiffness (SUCRA = 15.7%), physical function (SUCRA = 0.0%), and total WOMAC score (SUCRA = 7.8%). Tai Chi (TC) showed the highest likelihood of efficacy for Visual Analog Scale (VAS) outcomes (SUCRA = 17.4%), while weight-loss walking (LK) ranked first for Timed Up and Go (TUG) improvement (SUCRA = 27.1%). The comprehensive efficacy ranking was PT > LK > BD > YG > AT > WK > RW > TC > WQ > CY.

conclusionThis study demonstrates that Pilates appears to be the most effective aerobic exercise modality for managing knee osteoarthritis (KOA), particularly in enhancing overall functional outcomes. Tai Chi exhibited the greatest efficacy in reducing pain intensity, as quantified by the Visual Analog Scale (VAS). Based on these findings, Pilates and Tai Chi should be prioritized as primary therapeutic interventions for the majority of KOA patients.
