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

purposeIn recent years, medial meniscus (MM) posterior root tears (PRT) have received increasing attention due to their association with rapidly progressive knee osteoarthritis. MM posterior root (PR) repair has been reported to yield good clinical outcomes, but no study has yet to compare the postoperative outcomes after MMPR repair between sexes. The purpose of this study is evaluating the postoperative clinical outcomes following MMPR pullout repair by sex.

methodsEighty-six patients who underwent pullout repair for isolated MMPRTs at our institution between October 2016 and November 2019 were evaluated. Patients were divided into two groups according to sex, and their clinical outcomes were compared preoperatively and at 2 years postoperatively.

resultsThe cohort was comprised of 21 male and 65 female patients. Three factors related to physical status (height (p < 0.01), body weight (p < 0.01), and BMI (p = 0.02)) were significantly higher in male patients. No significant differences were observed in preoperative clinical scores between male and female. All clinical scores significantly improved at 2 years postoperatively in both sexes. In the clinical scores, the KOOS-symptom (p = 0.03), KOOS-QOL (p = 0.03), and Tegner activity scores (p < 0.01) showed significantly better scores in male patients.

conclusionFollowing MMPR pullout repair, the clinical outcomes significantly improved in both sexes. These results indicate that MMPR pullout repair is a universally effective technique regardless of the disadvantages of females in morphological characteristics.
