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

Purpose: To evaluate the impact anterior cruciate ligament reconstruction (ACLR) has on strike evasion rates, strike and landing rates, win percentage, and career longevity in Ultimate Fighting Championship (UFC) fighters. Methods: UFC fighters who underwent ACLR from 1993 to 2022 were matched 2:1 with uninjured controls. The percentage of each injured fighter's career that occurred before ACLR was deemed the "index percentage." Injured fighter performance pre-/post-ACLR was compared with control metrics pre-/postindex percentage. Results: Of the 82 patients with documented ACL injuries identified, 48 met the inclusion criteria. Of these, 27 returned for more than 2 fights and were paired with 54 controls. UFC fighters demonstrated return-to-sport rates of 81.25% and 56.25% for at least 1 and 2 fights, respectively. On average, it took 411.85 ± 174.73 (range, 165-879) days for fighters to return. All fighters had significantly lower evasion rates against total significant strikes, distance strikes, and head strikes, postindex ( Conclusions: In this study, we found that most UFC fighters who undergo ACLR return to sport for at least 1 fight; however, just over half return for at least 2 fights. There was not a significant difference in career length between fighters who returned to sport following ACLR for at least 2 fights and their controls. Defensive performance, but not offensive performance, declined significantly following ACLR. All fighters demonstrated significant declines in their win percentage as their career progressed, irrespective of ACLR. Level of Evidence: Level III, retrospective comparative study.
