Article in Zhongguo xiu fu chong jian wai ke za zhi = Zhongguo xiufu chongjian waike zazhi = Chinese journal of reparative and reconstructive surgery, 2022. 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
objectiveTo summarize the effectiveness of acetabulum reconstruction with autologous femoral head structural bone graft in total hip arthroplasty (THA) for Hartofilakidis type Ⅱ developmental dysplasia of the hip (DDH).
methodsA clinical data of 24 patients (27 hips) with Hartofilakidis type Ⅱ DDH, who underwent acetabulum reconstruction with autologous femoral head structural bone graft in primary THA between October 2012 and October 2020, was retrospectively analyzed. There were 3 males and 21 females, with an average age of 40 years (range, 20-58 years). The body mass index was 19.5-35.0 kg/m² with an average of 25.0 kg/m². There were 21 cases of unilateral hip and 3 cases of bilateral hips. The hip Harris score was 51.1±10.0. The leg length discrepancy of unilateral hip patients was (19.90±6.24) mm. The intraoperative blood loss, wound healing, and complications were recorded. The postoperative bone union, coverage rates of acetabular prosthesis and bone graft, and aseptic loosening of the prosthesis were evaluated based on X-ray films, and the improvement of hip function was observed by Harris score.
resultsThe intraoperative blood loss was 50-1000 mL (median, 350 mL). All incisions healed by first intention, and no fracture, hematoma, infection, or other complications occurred. Sciatic nerve injury occurred in 1 case (1 hip) and deep venous thrombosis occurred in 1 case (1 hip). All patients were followed up 15-103 months (median, 40.5 months). At last follow-up, Harris score was 92.6±4.1 and the difference was significant when compared with preoperative value (
conclusionFor Hartofilakidis type Ⅱ DDH patients, if the lateral acetabular prosthesis not covered by the host bone exceeds 5 mm in primary THA, autologous femoral head can be used for structural bone grafting, and the short- and mid-term effectiveness are favorable.
