Correlation of single-round strokes & performance indicators: Paris Olympic elite female golfers.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Despite golf's Olympic reinstatement, quantitative research on elite female Olympic golfers remains scarce, with most studies focusing on tour or amateur players. This study aimed to quantify relationships between single-round strokes and 13 performance indicators among top 10 2024 Paris Olympic female golfers (including ties), identify key predictors, and build a predictive model using correlation analysis, principal component analysis (PCA) and LASSO regression with leave-one-out cross-validation (LOOCV) and bootstrap validation to address overfitting concerns inherent to small-sample analyses. Results showed single-round strokes correlated negatively with GIR (r = -0.484), SG: Putting (r = -0.567) (both p < 0.01) and positively with Putt-Total (r = 0.582, p < 0.01). PCA extracted five principal components explaining 77.94% of total variance, representing distinct performance constructs. LASSO regression identified seven stable predictors (bootstrap selection frequency ≥ 90%): Greens in Regulation (100%), Putt-Total (99%), SG: Approach the Green (98%), SG: Around the Green (97%), SG: Putting (94%), SG: Off the Tee (92%), and Scrambling (88%). Model performance yielded an adjusted R² of 0.928 with cross-validated MSE of 0.528 based on 48 rounds from 12 golfers, though external validation is warranted. This study fills Olympic golf research gaps, providing evidence for targeted training and tournament strategy optimization.
