Mortality risk in osteoarthritis patients: a meta-analysis of observational studies.
Synthesis in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThis study aimed to evaluate the relationship between osteoarthritis (OA) and all-cause mortality, as well as cause-specific mortality.
methodsThis study was registered with PROSPERO (ID: CRD42024542643). A comprehensive literature search was conducted using Medical Subject Headings (MeSH) and keywords across PubMed, Embase, and the Cochrane Library databases, from inception to May 16, 2024. Study quality was assessed using the Newcastle-Ottawa Scale (NOS) and the Agency for Healthcare Research and Quality (AHRQ) criteria. Funnel plots and Egger’s test were used to assess publication bias. Statistical analyses were performed using STATA software version 14.0.
resultsTwenty-four observational studies (2003–2023) involving 465,555 OA patients were included. The pooled analysis revealed no significant association with all-cause mortality based on pooled estimates, although with very high heterogeneity [OR = 1.14, 95% CI (0.97, 1.35), I² = 98.2%, P = 0.119], but appeared to be associated with increased (CVD) mortality [OR = 1.15, 95% CI (1.07, 1.24), I² = 73.5%, P < 0.001]. There was no increased risk of cancer mortality [OR = 1.02, 95% CI (0.94, 1.11), I² = 69.4%, P = 0.000]. Subgroup analysis indicated no significant gender-based differences in all-cause mortality, nor in radiographic OA. However, symptomatic OA and knee/foot OA were associated with a markedly higher risk of all-cause mortality. Regional analysis showed no significant variation across Europe, Asia, or North America. Sensitivity and subgroup analyses confirmed the results, with no evidence of publication bias.
conclusionsThis meta-analysis suggests that osteoarthritis is not associated with all-cause mortality but is but is associated with a modest increase in CVD mortality. There is no relationship between OA and cancer mortality. These findings emphasize the importance of focused care and lifestyle modifications to mitigate cardiovascular risks in OA patients.
