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

Background: Return to play and performance following elbow ulnar collateral ligament (UCL) reconstruction or repair in Major League Baseball (MLB) position players have not been well studied. Purpose: To evaluate return to play and return to performance using modern advanced analytics at 1 and 2 seasons following UCL surgery in MLB position players. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective analysis was performed on all 33 MLB position players who underwent primary UCL surgery between March 1, 2014, and November 1, 2024. Incidence, risk factors, and return-to-play rates were recorded. Return-to-performance analysis was conducted for 25 players who met the inclusion criteria and were compared to preoperative levels and 50 uninjured matched controls. Performance data were collected for all MLB position players using public sources. Binary logistic regression was also conducted. Results: Incidence of UCL surgery in MLB position players over the full 11-season period (2014-2024) was 2.9 ± 1.4 surgeries per season in our cohort, with an even greater average in the past 5 full seasons compared to 2014 to 2019 ( Conclusion: Annual UCL surgery rates in MLB position players have tripled in recent seasons. Less contact and defensive ability were associated with getting UCL surgery. Over 80% of players returned to play by 1.5 years postoperatively, with those who underwent UCL repairs returning faster. Most performance metrics return at high rates, but the significant decline in player value after returning can likely be explained by decreased workload and possibly a slight decline in offensive performance.
