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

caseTwo women (aged 35 and 29 years) with intractable chronic knee infection of tumor prostheses opted for amputation. As only the trochanteric region could be preserved, we resected the remaining proximal femur and created a 15-cm long stump using unaffected proximal thigh soft tissue to avoid the drawbacks of ultra-high-thigh amputation and conventional hip disarticulation. Both had no contracture, could move their stump voluntarily, and ambulated using a standard transfemoral prosthesis without a pelvic belt at 4-year and 3-year follow-ups, respectively.

conclusionOur procedure might benefit patients who require ultra-high-thigh amputation, with preservation of only the femoral trochanteric region.
