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

background and purposeCurrently, there is no specific surgical treatment strategy established for spastic hip displacement in ambulatory patients with cerebral palsy. We aimed to evaluate the outcomes of our hip reconstructions, specifically designed to address hip displacement within the context of single-event multilevel surgery (SEMLS).

methodsWe conducted a retrospective study on patients with Gross Motor Function Classification System (GMFCS) levels II (n = 27) and III (n = 28). Surgical procedures involved various combinations of open or closed reduction, iliac osteotomy, proximal femoral derotational osteotomy, distal femoral derotational and shortening osteotomy, and proximal femoral varus derotational osteotomy. The overall developmental status of the hip was assessed using the Melbourne Cerebral Palsy Hip Classification Scale (MCPHCS) at a mean age of 17.3 years (SD 4.7).

results73 hips in 55 patients were included. They underwent hip reconstruction at a mean age of 9.7 years (SD 2.6). 69 of 73 hips achieved successful outcomes. Before surgery, 51 hips had a migration percentage (MP) of 30-60%, 21 had 60-100%, and 1 hip > 100%. At the final follow-up, 12 hips were classified as MCPHCS grade 1 (MP < 10%), 36 as grade 2 (10-15%), 21 as grade 3 (15-30%), 3 as grade 4 (30-60%), and 1 as grade 5 (60-100%). 52 patients either maintained or improved their preoperative GMFCS levels.

conclusionWithin the SEMLS framework, our tailored hip reconstruction achieved satisfactory hip outcomes in 69 of 73 hips and resulted in sustained improvement in hip stability at long-term follow-up.
