Clinical efficacy of robot-assisted total hip arthroplasty for developmental dysplasia of the hip: A meta-analysis.
Synthesis in Joint diseases and related surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
objectivesThe aim of this meta-analysis was to compare the clinical efficacy of robot-assisted total hip arthroplasty (R-THA) versus conventional total hip arthroplasty (C-THA) for the treatment of developmental dysplasia of the hip (DDH). MATERIALS AND
methodsEligible articles published until May 2025 were searched from the Cochrane Library, Web of Science, PubMed, Embase, ScienceDirect, and Springer. Search terms included "robot-assisted", "developmental dysplasia of the hip", "total hip arthroplasty", using mean differences (MDs) and risk differences (RDs) as combined variables, and selecting 95% as the confidence interval (CI).
resultsSeven clinical studies with a total of 876 patients were finally included in this study. There were no significant differences between the two groups in terms of cup inclination (MD=0.07; 95% CI: -0.95 ~ 1.10; p=0.89), cup anteversion (MD=-4.02; 95% CI: -9.59 ~ 1.55; p=0.16), intraoperative bleeding (MD=11.25; 95% CI: -56.02 ~ 78.52; p=0.74), operative time (MD=3.03; 95% CI: -15.66 ~ 21.72; p=0.75), postoperative complications (dislocation [RD=-0.01; 95% CI: -0.03 ~ 0.01; p=0.26], deep infection [RD=0.01; 95% CI: -0.01 ~ 0.02; p=0.37] and nerve injury [RD=0.01; 95% CI: -0.01 ~ 0.03; p=0.56], revision/reoperation [RD=-0.00; 95% CI: -0.03 ~ 0.03; p=1.00], and absolute vertical distance of center of rotation [COR] [MD=-0.50; 95% CI: -1.07 ~ 0.06; p=0.08]). However, compared to the C-THA group, the R-THA group showed significantly higher Harris Hip Score (HHS) (MD=2.17, 95% CI: 0.11 ~ 4.22, p=0.04) and more accurate placement of the horizontal COR (MD=-0.77; 95% CI: -1.21 ~ -0.32; p=0.0008).
conclusionIn the R-THA group, the accuracy of horizontal placement of the COR was moderately improved, and the postoperative HHS was higher than that in the C-THA group, although such differences might not be obviously perceived by patients. Additionally, no significant differences were found between the two groups in other surgery-related parameters and safety.
