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 compare contact stresses between Attune® and PFC Sigma® total knee arthroplasty (TKA) implants in the presence of knee malalignment.

methodsMaximum contact stress after finite element analysis were compared during standing, walking, and stair climbing in 0°, 2.5° and 5°varus/valgus knee alignments.

resultsThe percentage increase in contact stress was highest during walking with PFC Sigma® in 5° varus (238.5%), standing with Attune® in 5° valgus (127.2%), and standing with Attune® in 2.5° valgus (107.8%).

conclusionThe newer Attune® design may be associated with higher maximum contact stresses and increased risk of wear and implant failure.
