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

introductionA novel hand-held navigation combines gyroscopes, accelerometers and a secure local wireless channel to guide the distal femoral and proximal tibial cutting positions by displaying to the surgeon directly on the pods within the surgical field. No previous study has reported on its accuracy. MATERIALS AND

methodsA prospective randomized controlled trial was performed to compare radiographic outcomes in minimally invasive surgery total knee arthroplasty (MIS-TKA) with (40 patients, 40 knees) and without (40 patients, 40 knees) the novel hand-held navigation.

resultsThe use of hand-held navigation resulted in fewer outliers (> ± 3° malalignment) in all frontal alignment: the hip-knee-ankle, the femoral component, and the tibial component. Tibial slope was also better achieved with the navigation. Femoral component flexion was not significantly different. Operation time and bone cutting time with the navigation were not longer than those without. Blood loss from drainage was not significantly different.

conclusionThe hand-held navigation improves accuracy for mechanical alignment and positioning of the prosthesis without additional surgical time.
