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

backgroundThe ligamentum teres (LT) has received attention in patients undergoing hip arthroscopy (HA) for femoroacetabular impingement (FAI). Indeed, a better understanding of the function of the LT and its implications for clinical outcomes in the presence of a torn LT is required. This systematic review analyses the patient-reported outcome measures (PROMs) and the complication rate when an intact or torn LT is encountered during HA for FAI.

methodsStudies that compared patients with an intact to those with a torn LT managed with debridement during hip arthroscopy for FAI were identified from the Web of Science, PubMed, and Embase. The minimum follow-up for inclusion was 24 months. The Risk of Bias in Non-randomised Studies of Interventions (ROBINS-I) tool was used to assess the risk of bias. Patient characteristics and PROMs were assessed at the baseline and last follow-up.

resultsThe systematic review identified two studies comprising 611 patients. No statistically significant difference was found in pain, Harris Hip Score, and the activities of daily living and sports subscales of the Hip Outcome Score between patients with an intact LT and those with a torn LT treated with debridement, both of whom underwent HA for FAI.

conclusionsIn patients undergoing arthroscopic management for FAI, an intact or torn ligamentum teres managed with debridement does not influence postoperative PROMs. Given the importance of the LT as a structure of the hip joint and the increasing interest in HA for FAI, further standardised studies will be a valuable source for surgeons encountering this pathology.
