Evaluating Spin Bias in the Abstracts of Systematic Reviews and Meta-Analyses on Robotic-Assisted Total Hip Arthroplasty: A Systematic Review.
Review in HSS journal : the musculoskeletal journal of Hospital for Special Surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Interest in robotic-assisted total hip arthroplasty (RA-THA) continues to grow, despite inconsistent evidence on its effectiveness. Purpose: We sought to assess for the presence of spin bias in abstracts of systematic reviews and meta-analyses (SRMAs) comparing RA-THA to conventional total hip arthroplasty (C-THA). Methods: We conducted a systematic review of studies identified in a comprehensive search of MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews from each database's inception to June 23, 2025. Search terms included "robotic," "hip," "arthroplasty," "systematic review," and "meta-analysis." Inclusion criteria were (1) SRMAs evaluating outcomes of RA-THA, (2) studies comparing RA-THA to conventional techniques, and (3) publications in English. Studies were excluded if they (1) assessed RA-THA with other robotic-assisted joint arthroplasty procedure, or (2) assessed RA-THA surgery alongside other technologies. Abstracts were assessed for the 15 most severe forms of spin as defined by Yavchitz et al. Methodological quality was assessed using the AMSTAR 2 (A Measurement Tool to Assess Systematic Reviews-2) tool. Results: Twelve SRMAs were eligible for inclusion. Eleven SRMAs (91.7%) contained at least 1 of the 15 most severe forms of spin. Type 3 spin ( Conclusion: This systematic review found there is a high prevalence of spin bias in abstracts of SRMAs evaluating RA-THA. The most common type of spin involved selective reporting of outcomes favoring RA-THA (type 3). Future SRMAs can minimize spin by presenting balanced reporting of efficacy, or lack thereof, in their abstracts and strengthen methodological rigor by consistently reporting study funding sources. Level of Evidence: Level IV, Systematic review of level-I to level-IV studies.
