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: Insertional Achilles tendinopathy (IAT), often associated with Haglund deformity, is a common cause of posterior heel pain, with up to 40% of patients requiring surgical intervention after unsuccessful conservative treatment. Bioinductive collagen scaffolds have been proposed as a potential adjunct for tendon healing. Purpose: To evaluate clinical and structural outcomes after open IAT surgery with and without scaffold augmentation. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective comparative cohort study was conducted between 2021 and 2024, including 30 consecutive patients (30 ankles) who underwent open IAT surgery with Haglund resection and double-row tendon reattachment performed by a single surgeon. Fifteen patients underwent standard repair, and 15 received additional augmentation with a bioinductive collagen scaffold. Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) and Pain Interference (PI) scores were collected preoperatively and at 6, 12, and 18 months postoperatively. Magnetic resonance imaging (MRI) was obtained at study enrolment (baseline) and repeated at 12 months after surgery. Secondary outcomes included time to return to sport (RTS), and all postoperative complications were recorded. Minimal clinically important difference thresholds of 5 to 8 points for PF and 8 to 10 points for PI were applied. Statistical analysis included between-group comparisons at each time point and evaluation of changes over time, with significance set at Results: Preoperative PROMIS scores were similar between groups (PF: 39.8 ± 5.7 vs 40.4 ± 6.1; PI: 64.1 ± 6.4 vs 63.7 ± 5.9). At 6 months, both groups improved, with greater change in the scaffold group (PF: 54 ± 5.3 vs 49.5 ± 6; Conclusion: Our study shows that bioinductive scaffold augmentation in open IAT surgery is safe and may be associated with earlier improvements in pain, function, and RTS, while longer-term outcomes are similar to standard repair. These findings suggest a potential role for this approach in active individuals seeking a faster recovery.
