Femoral stem size mismatch in women undergoing total hip arthroplasty.
Article in Journal of orthopaedics, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundTotal hip arthroplasty (THA) is a highly successful surgery with a high prevalence in women. Women have been noted to have smaller proximal femoral anatomy and decreased bone strength compared to males. The goal of our study was to define the size discrepancy in femoral stem implants between men and women using a metaphyseal fitting single taper stem.
methodsWe retrospectively reviewed the THA's performed by a single surgeon over the previous two years. Data was extracted from operative reports regarding stem size, neck length and offset, and conversion to a different type of stem. This data was reviewed with confidence intervals and a
resultsWe analyzed the data from 276 THA's performed (129 in men, and 147 in women). Women were noted to be associated with smaller stem sizes compared to men (37.67% in women, 6.11% in men), with 7.48% of women requiring conversion to a different type of implant. There was a significant difference in mean stem size (9.21 in men, 6.70 in women, p < 0.0001). Women also required reduced neck options significantly more often than men (38.97% in women, 9.29% in men, p < 0.0001).
conclusionReview of femoral stem sizes reveals that current femoral stem sizing may not appropriately account for women and alternative stem options should be available if using a metaphyseal fitting single tapered stems. Future consideration should be given to more anatomic female sized femoral stems or alternative options should be available.
