The varus cemented femoral stem in total hip arthroplasty: Predictors, implications and The Femoral Access Ratio.
Article in Journal of orthopaedics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
introductionWe describe a novel morphological ratio, the Femoral Access Ratio, in the preoperative femur to investigate the predictors of femoral stem malalignment.
methodsWe reviewed 70 cemented femoral stems. Preoperative 'FAR' score was measured. Postoperative coronal stem alignment was measured and ten year survivorship and functional outcomes investigated.
resultsThere were three predictors of varus stem malalignment-BMI, GT-height and 'FAR' score. Increasing BMI led to higher rates of malalignment (p = 0.048). 'FAR' score <1 lead to 68.4% of varus stems. GT height contributed most to the prediction of varus stem malalignment (p = 0.013).
conclusionFAR score is a simple preoperative radiographic measurement that can predict the likelihood of femoral stem varus malalignment in cemented femoral stems.
