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

purposeThe purpose of this study is to assess whether early surgical intervention for first-time patellar dislocations in paediatric patients is superior to conservative management. We hypothesized that surgical intervention would lead to lower redislocation rates compared to conservative treatment.

methodsThree online databases (PubMed, MEDLINE and EMBASE) were searched from inception to 14 March 2024 to identify studies investigating the management options for acute first-time patellar dislocations in paediatric patients. Data pertaining to patient demographics, patient management, redislocation rates and Kujala scores, evaluating function, were abstracted. Weighted means and meta-analyses were conducted to compare rates of redislocation, as well as Kujala scores. The quality of included studies was assessed using the methodological index for non-randomized studies criteria for non-randomized studies and the ROB2 tool for randomized controlled trials (RCTs).

resultsA total of 11 studies and 761 patients were included in this review. The weighted mean post-operative combined rates of redislocation in the surgical group was 25.1%, compared to 46.4% in the conservative group at a mean follow-up of 53.2 months (12-168). The relative risk (RR) of redislocation was 0.82 (95% confidence interval [CI]: 0.65-1.04, I

conclusionSurgical management for first-time patellar dislocations in a paediatric population, particularly MPFLR, may be more beneficial in lowering redislocation rates than conservative management. No significant differences in Kujala scores were found. LEVEL OF EVIDENCE: Level IV.
