The Sacro-Femoral-Pubic Angle May Estimate Pelvic Tilt in Patients with Severe Developmental Dysplasia of the Hip and Leg Length Discrepancy Undergoing Total Hip Arthroplasty.
Article in Clinics in orthopedic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Spinopelvic movement disorders are associated with instability after total hip arthroplasty (THA). In patients with Crowe type 3-4 developmental dysplasia of the hip (DDH) and leg length discrepancy (LLD), sagittal radiographs may not allow accurate assessment of spinopelvic motion. This study aimed to evaluate the sacro-femoral-pubic (SFP) angle, a coronal plane parameter, as a predictor of calculated pelvic tilt (PT). Methods: Thirty-two patients with neglected unilateral Crowe type 3-4 DDH who underwent THA were retrospectively analyzed. Preoperative SFP angle and sacral slope (SS) were measured, and preoperative PT was calculated using postoperative pelvic incidence and preoperative SS values. Results: The SFP angle showed a strong negative correlation with calculated PT ( Conclusions: The SFP angle may serve as an indirect surrogate for calculated PT in patients with Crowe type 3-4 DDH and LLD when preoperative sagittal spinopelvic assessment is not feasible prior to THA or spinal deformity surgery.
