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
Visual attention plays a crucial role in basketball shooting, yet how it adapts under varying exercise intensities and from different shooting positions remains poorly understood, especially in elite female athletes. This study examined the effects of exercise intensity (low, moderate, high) and shooting position (left 45°, 90°, right 45°) on fixation behavior and 2‑point shooting accuracy in elite female basketball players. Twenty‑two players from a championship‑winning university team performed two‑point shots from three positions under three intensity conditions, each defined by heart‑rate zones (%HRmax). Fixation metrics (number of fixations, fixation duration, distribution) were recorded using Tobii Glasses 3. Data were analyzed using two‑way repeated‑measures ANOVA and generalized linear mixed‑effects models (GLMMs) with a binomial distribution for trial‑level accuracy; Pearson correlations are reported descriptively. Exercise intensity significantly influenced all fixation metrics. High intensity led to increased fixations across all areas of interest (hoop, backboard, net) and longer total fixation duration, indicating higher cognitive load. Moderate intensity was associated with the lowest total number of fixations and shortest duration, reflecting efficient visual processing. Shooting position also affected fixation: the 90° position attracted the most fixations and longest duration on the hoop (F = 4.56, p = 0.017, [Formula: see text] = 0.19, 95% CI [0.02, 0.37]), while the 45° positions shifted attention toward the backboard. Fixation duration on the hoop positively correlated with accuracy under high intensity (r = 0.499, p = 0.021, 95% CI [0.10, 0.76]), whereas number of fixations negatively correlated with accuracy across intensities. Moderate intensity promotes optimal visual‑attentional control and shooting accuracy in elite female athletes, whereas high intensity disrupts fixation stability and increases cognitive load. Position‑specific adaptations in visual strategy were also observed. These findings support the use of intensity‑ and position‑based visual training to enhance shooting performance under realistic game conditions.
