Functional implications of femoral offset following hemiarthroplasty for displaced femoral neck fracture.
Observational study in International orthopaedics, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 papers, 2 of them syntheses that pooled 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.
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
purposeInadequate reconstruction of femoral offset after total hip arthroplasty (THA) is associated with unfavourable outcomes, but its importance following hemiarthroplasty for displaced femoral neck fracture is unknown.
methodsOur study examined the correlation between reconstructed femoral offset and functional outcome 12 months after post traumatic hemiarthroplasty in 126 prospectively enrolled elderly patients. Rotation-corrected femoral offset (FORC), relative femoral offset (FORL) and contralateral femoral offset (FOC) were measured on anteroposterior radiographs. The Harris Hip Score (HHS) was the primary outcome measure; the timed up and go (TUG) test and Lawton instrumental activities of daily living (IADL) score were secondary outcomes. Correlations were sought using the Spearman correlation coefficient (r). Sample size was calculated using an Altman nomogram, with the power set at 80 %, the significance level of 0.05 and a standardised difference of 0.75.
resultsThe mean reconstructed FORC was 41 mm (17-67 mm) and showed a linear relationship and excellent correlation with the FOC. At 12 months, we found a significant positive correlation between FORC and HHS (r = 0.303, p = 0.025) and IADL (r = 0.325, p = 0.013), but not TUG (r = -0.026, p = 0.863). These findings were confirmed by bivariate and multivariate correlation between FORL and functional outcome parameters.
conclusionsWe found a clinically relevant relationship between femoral offset and functional outcome after hemiarthroplasty in elderly patients, comparable with that of THA, for treating osteoarthritis.
