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: Complex revision total hip arthroplasty poses challenges in cases of severe acetabular bone loss, pelvic discontinuity, or multiple prior revision total hip arthroplasties. This study compares clinical outcomes and implant survivorship between custom triflange acetabular implants (CTAIs) and standard off-the-shelf cup-cage constructs. Methods: Between 2016 and 2022, our registry was screened for consecutive patients who received either a CTAI or an off-the-shelf cup-cage construct. A retrospective review assessed patient characteristics, perioperative data, and postoperative outcomes using radiographs and follow-up notes. Primary outcomes were postoperative mortality and reoperation rates. Secondary outcomes included implant migration, bony remodeling, and patient-reported outcomes using Hip Disability and Osteoarthritis Outcome Score for Joint Replacement (HOOSJR). Kaplan-Meier survival analysis assessed mortality-free survival and implant survivorship. Univariate and multivariate analyses was conducted to determine associations between preoperative variables and postoperative outcomes. Results: Among 787 screened patients, 18 met inclusion criteria. Fourteen (78%) had Paprofsky type 3A (28%) or 3B (50%) defects. Eleven (61%) patients received a CTAI, while 7 (39%) received standard off-the-shelf cup-cage constructs. The ΔHOOSJR scores were 37.7 ± 42.4 for off-the-shelf cup-cage constructs and 48.7 ± 30.8 for CTAI, with no significant difference ( Conclusions: Off-the-shelf cup-cage constructs and CTAIs demonstrated comparable short-term clinical outcomes and implant survivorship in this cohort of patients undergoing complex revision THA. Implant selection may therefore be guided by patient-specific factors and surgeon preference.
