1 · What the graph read from it

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.

2 · The registry

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

purposeTo compare functional, radiographic, and safety outcomes between internal brace (IB) augmentation and modified Broström-Gould (MBG) repair for chronic lateral ankle instability (CLAI), and to determine whether IB provides clinically relevant advantages over conventional anatomic repair.

methodsA systematic review and meta-analysis was conducted in accordance with PRISMA 2020 and prospectively registered in PROSPERO. PubMed/MEDLINE, Embase, Cochrane CENTRAL, Web of Science, and Scopus were searched from inception to January 2026. Randomized controlled trials and observational studies comparing IB augmentation with MBG repair for CLAI were included. The primary outcome was the Foot and Ankle Ability Measure (FAAM) Sports score. Secondary outcomes included Foot and Ankle Outcome Score (FAOS), American Orthopaedic Foot & Ankle Society (AOFAS) score, return-to-sport time and rate, complications, recurrence, talar tilt angle (TTA), anterior talar translation (ATT), and operative time. Risk of bias was assessed using RoB 2 and ROBINS-I. Random-effects meta-analyses were performed.

resultsThirteen comparative studies involving 1,015 patients (472 IB, 543 MBG) were included. IB was associated with a significant improvement in FAAM Sports score versus MBG (mean difference [MD] + 4.59; 95% confidence interval [CI] + 1.35 to + 7.82; I²=67.1%). After exclusion of a young female-specific cohort, the effect increased (MD + 6.06; 95% CI + 4.26 to + 7.86; I²=0%). Descriptively, IB patients returned to sport 4-8 weeks earlier than MBG patients across two studies; formal meta-analysis was not performed owing to the limited number of studies (k = 2). No significant between-group differences were observed for FAOS, AOFAS, return-to-sport rate, complications, recurrence, TTA, ATT, or operative time.

conclusionIB augmentation was associated with better sports-specific function and earlier return to sport than MBG repair in patients with CLAI, without evidence of inferior radiographic or safety outcomes. These findings support IB as a useful surgical option, particularly for active patients in whom recovery trajectory and return to sport are important clinical priorities. REGISTRATION: This systematic review and meta-analysis was prospectively registered in PROSPERO (Registration No. CRD420261355719; registration date: 30 March 2026).
