1 · What the graph read from 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.

2 · The registry

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 investigate the clinical efficacy and safety of two different bone graft materials in the minimally invasive treatment of early and middle stage femoral head necrosis.

methodsA total of 36 patients (39 hips) with avascular necrosis of the femoral head were divided into autologous iliac bone group (ABG) and bioceramics bone group (BBG). Both groups were treated with minimally invasive thick channel decompression to remove dead bone of femoral head. The ABG was treated with autologous iliac bone graft, and BBG was treated with β-tricalcium phosphate bone graft. The operation time, intra-operative blood loss, haemoglobin, and haematocrit were recorded at three and seven days post-operatively. The clinical efficacy and safety were evaluated by Harris score and imaging examination before, and after treatment and at follow-up stages.

resultsThe patients were followed up for 24 to 45 (average 29.27 ± 3.56) months. The BBG was significantly better than the ABG in terms of operation time, intra-operative blood loss, haemoglobin, and haematocrit value at three days. Compared with pre-operative, the Harris score of the two groups at 12 months after operation was significantly improved. The Harris score and the imaging evaluation of the last follow-up exhibited significantly better outcome in BBG than those of ABG.

conclusionBioceramics and autologous iliac bone minimally invasive treatment of early and medium-term femoral head necrosis exhibited satisfactory clinical efficacy in the short and medium-term. The bioceramics graft materials have the advantages of reducing trauma, bleeding, operation time, and quick recovery of post-operative functions.
