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

backgroundTranstrochanteric rotational osteotomy (TRO) for osteonecrosis of the femoral head (ONFH) is considered technically demanding, with varying results among institutions. This is due to the complex soft tissue exposure and determination of the osteotomy line. We report a case in which the osteotomy line was assessed using the Stryker OrthoMap CASE PRESENTATION: The patient was a 24-year-old male with alcohol-related ONFH. Japanese Investigation Committee Classification Type C2/C2 Stage 3b/3b was confirmed through magnetic resonance imaging, and TRO was performed bilaterally on the same day using the Stryker OrthoMap

conclusionsThis is the first report of a bilateral TRO for bilateral ONFH performed on the same day using CT-based navigation. For osteonecrosis, which is often bilateral, accurate determination of the osteotomy line as planned preoperatively using CT-based navigation contributes to shorter operative time, less intraoperative blood loss, and allows for bilateral same-day surgery. This may improve situations in which patients are hesitant to undergo bone-preserving surgery because of the long period of time required to return to work, thereby facilitating their early reintegration into society.
