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
Objective: To compare the clinical efficacy of rotational osteotomy at the base of femoral neck and iliac bone flap transfer with ascending branch of lateral femoral circumflex artery(vascularized iliac bone flap transfer) in the treatment of ARCO III stage, CJFH-L type osteonecrosis of femoral head. Methods: We compared 25 cases (Group A), in which 25 hips underwent rotational osteotomy at the base of femoral neck and 25 cases (Group B), in which 25 hips underwent vascularized iliac bone flap transfer in our hospital from September 2017 to March 2024.The operative time and hospitalization time were compared, the collapse and repair of femoral head and the healing of osteotomy were evaluated Results: All operations were conducted successfully in both groups. The follow-up time was 36.2 ± 21.62 months. The operation time in Group A was (215.20 ± 56.80) minutes, which was longer than that in Group B (183.96 ± 32.14) minutes ( Conclusion: Both rotational osteotomy of the base of the femoral neck under surgical dislocation and vascularized iliac bone flap transfer can obtain satisfactory short-term results in the treatment of CJFH-L type, ARCO III stage osteonecrosis of the femoral head. Rotational osteotomy at the base of femoral neck under surgical dislocation can be chosen to delay the collapse process for CJFH-L2 type, ARCOⅢB stage ONFH. Vascularized iliac bone flap transfer has the advantage of short operation time. It is easier and suitable for CJFH-L1 type, ARCOⅢA stage ONFH.
