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

backgroundThere is still a lack of clinical data in arthroscopic treatment for treating multiple ligament injuries. This study aims to evaluate the clinical outcomes of patients with multiple ligament injuries undergoing treatment based on the classification stage and type of injury.

methodsA prospective, clinical trial on multiple ligament injuries was planned, which included 95 patients (58 men and 37 women; age: 42.8 ± 11.9 [range, 18-63] years) from October 2017 to June 2018. Injuries were classified into three stages (emergency stage < 24 h; acute stage: 24 h to 3 weeks, and chronic stage: > 3 weeks) and six types (KD I-VI) based on injuries time and structures, which indicated appropriate treatments. The clinical outcomes were evaluated at 2, 4, 6, 8, and 12 weeks and at 6, 9, 12 months and 24 months after surgery. The final choices in efficacy index included International Knee Documentation Committee (IKDC) score, Lysholm score, visual analog scale (VAS) score, and range of motion.

resultsDuring the follow-up, all patients exhibited statistically significant functional improvement in the injured limb compared with their preoperative situation. The mean postoperative scores of acute stage patients at 2-year follow-up were IKDC subjective score, 77.54 ± 11.53; Lysholm score, 85.96 ± 9.39; Tegner score, 4.13 ± 1.08; and VAS score, 1.21 ± 0.76. The mean postoperative scores of chronic stage patents at 2-year follow-up were IKDC subjective score, 74.61 ± 12.38; Lysholm score, 81.71 ± 10.80; Tegner score, 3.96 ± 1.14; and VAS score, 1.71 ± 0.60. The IKDC subjective score, Lysholm score, and Tegner score were significantly improved (P < 0.01) and the VAS score was significantly decreased (P < 0.01) at 2-year follow-up. Regarding the multiple ligament injuries classification, patients with more structural damage in stages V and VI showed less progress in functional recovery than those in stages I-IV.

conclusionsThis new classification with three stages and six types helps to identify the severity of injury and plan the management effectively. The outcomes were encouraging and the subjective functional results showed significant improvement at 2-year follow-up. STUDY
