Adipose-derived stromal vascular fraction injection following core decompression and biochemistry artificial bone graft implantation in osteonecrosis of the femoral head.

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
purposeTo determine how adipose-derived stromal vascular fraction (SVF) injection following core decompression (CD) and biochemistry artificial bone graft implantation affects outcomes in patients with osteonecrosis of the femoral head (ONFH).
methodsA total of 19 patients (28 hips) with stage I-IIIA ONFH received adipose-derived SVF injection and combined core decompression and biochemistry artificial bone graft implantation, followed up for a minimum of two years. Disease progression was evaluated according to the Association Research Circulation Osseous (ARCO) staging system, and the change of the ratio of the necrotic volume to femoral head volume was calculated with MRI before and after operation.
resultsAt the last follow-up, 15 hips remained stable, and 13 hips had a progression, according to the ARCO staging system. A total of eight hips (5 with ARCO stage II and 3 with staged IIIA at baseline) progressed to post-collapse stage (stage IIIB-IV). In total, seven of eight hips with post-collapse stage and one with IIIA stage at follow-up converted to THAs in an average of 17.5 months (range, 11-68 months) postoperatively. The mean ratio of the necrotic lesion volume to the femoral head significantly decreased in hips with ARCO stage I (17.9 ± 3.0% to 9.8 ± 1.3%, p = 0.012, Δ necrosis ratio = 8.1 ± 4.2%) and stage II (22.7 ± 6.3% to 17.1 ± 9.4%, p = 0.001, Δ necrosis ratio = 5.7 ± 6.6%) at baseline. For the eight hips that progressed to post-collapse stage, the mean necrosis ratio increased from 27.4 ± 5.4% to 31.1 ± 4.0% (p = 0.146), Δ necrosis ratio = - 3.7 ± 3.9%. For the other 20 hips radiological survived, the mean necrosis ratio improved from 19.9 ± 4.4% to 11.8 ± 3.3% (p < 0.001), with Δ necrosis ratio = 8.1 ± 4.9%.
conclusionAdipose-derived SVF injection following core decompression and biochemistry artificial bone graft implantation is safe and could effectively repair the necrosis lesion and delay disease progression in patients with early-stage ONFH.
