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
backgroundThis study aims to investigate whether individualized component positioning in robotic-assisted total hip arthroplasty (RTHA) using three-dimensional (3D) Functional Component Positioning Assessment (FCPA) reduces prosthetic and bone impingement and improves Patient-Reported Outcome Measures (PROMs).
methodsThis retrospective study includes 100 consecutive patients who underwent RTHA at a single center between May 2021 and March 2022 using the Mako THA system. Preoperative imaging and planning incorporated sacral slope (SS) measurements. SS values in standing and sitting positions were uploaded into the robotic software to simulate prosthetic hip motion during FCPA and guide component orientation. The primary outcome measures included intraoperative impingement analyses using FCPA and postoperative PROMs, including the Oxford Hip Score (OHS), Forgotten Joint Score (FJS-12), and Hip Disability and Osteoarthritis Outcome Score (HOOS).
resultsImpingement was detected in 46% of patients during daily living activities, with prosthesis-on-prosthesis being the most frequent impingement type. No statistically significant differences in PROMs were observed between patients with and without impingement. Nonetheless, overall PROMs were excellent, with a mean HOOS of 94.2 ± 8.3, mean FJS-12 of 87.8 ± 17.2, and mean OHS of 92.3 ± 10. Multivariate analysis revealed that higher BMI negatively impacted PROMs, and the SS difference correlated significantly with OHS and FJS-12 scores (P < 0.0001).
conclusionsIndividualized component positioning, even when aided by 3D FCPA, does not eliminate the risk of impingement. The concept of a universal "safe zone" may be inadequate to prevent impingement, emphasizing the need for patient-specific implant positioning strategies based on spinopelvic mobility. While impingement did not significantly impact PROMs, optimizing implant positioning through robotic-assisted techniques may contribute to improved long-term outcomes and reduced dislocation risk.
