Physical Strength Is Not Associated With Facial Sexual Dimorphism and Asymmetry in Either Czechs or Cameroonians.

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
objectivesHandgrip strength is a widely used indicator of muscle strength and general health, but its association with facial morphology remains unclear. This study examined whether handgrip strength or its asymmetry is related to facial sexual shape dimorphism, perceived masculinity/femininity, and facial asymmetry in two culturally and genetically distinct populations: Cameroonian and Czech adults.
methodsGeometric morphometric methods were applied to full-face portraits of 226 individuals (balanced by sex, aged 19-59), using 72 facial landmarks and semi-landmarks. Pearson correlations and a series of ANOVA analyses were then used to assess possible associations between facial traits and both absolute and asymmetric grip strength.
resultsAcross all models and subgroups, associations between handgrip strength and facial morphology were weak and nonsignificant. None of the facial characteristics reliably predicted either handgrip strength or its asymmetry in either men or women.
conclusionsThese findings suggest that facial morphology on its own does not reliably reflect muscular strength. Further research should incorporate longitudinal and cross-cultural designs.
