As a team leader, a coach plays a significant role in helping his/her players obtain high levels of performance and success; therefore, a coach should possess skills to help his/her athletes accomplish such daunting tasks. We conducted a metaanalysis to evaluate the relationship between coaching behaviors, athlete satisfaction, and team cohesion. Moreover, we examined gender as a possible moderating variable. Two-hundred eighty-eight effect sizes were obtained from 24 studies that used Chelladurai's sports leadership scale. Overall, a moderate relationship was found between leadership and cohesion, and a large relationship was found between leadership and satisfaction. Training/instruction was the highest contributor for both relationships. Gender moderated both relationships. It is important to recognize the influence leadership behaviors have on the psychological state of players, especially as sports evolve to be more challenging and multifaceted.

Our data suggested that periodontitis is independently associated with non-fatal stroke, and its impact seems to be greater among younger or normotensive Korean adults.

Obesity was associated with periodontitis. VFA was the most suitable indicator of obesity in relation to periodontitis. Obesity may be a substantial risk factor for periodontitis.

OHIP-K showed excellent reliability and validity. OHIP-14S may be a better choice for the evaluation of oral health-related quality of life among the Korean elderly for an international comparison.

These results suggest that periodontitis could be an independently related factor on MetS. Hence, dentists and physicians should be aware of the importance of periodontitis as a potential source of inflammatory burden.
