Outcomes following a 'positive' response to diagnostic intra-articular hip injection for pre-arthritic hip pain based on the level of percent pain improvement.
Review in Journal of hip preservation 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
Diagnostic hip injections are used to confirm an intra-articular source of hip pain in adolescents and young adults in order to guide management. There is currently no data-driven consensus regarding what cutoff metric should be used to constitute a 'positive' response to injection. This study compared using either 50% or 75% immediate pain improvement to define a positive response to fluoroscopically-guided diagnostic hip injection to aid in management decision-making. Rates of surgical management and likelihood of satisfaction with care at 12+ months were then compared between the two groups. Amongst 56 hips, (mean age 18.5 (SD ± 5.2) years, 89% (50/56) female) there was no difference in the rate of progression to surgery amongst responders when using either a ≥50% or ≥75% cutoff of pain improvement (71% (29/41) versus 74% (20/27), between-group difference 3% [95% CI, -18% to 25%],
