The modal version of the model matches a more computationally expensive sectional scheme50.
During Thomas's 13 years coaching the Haldane girls, the team was 274-39 with 10 league, 10 sectional, 10 regional, 4 state and 3 federation championships.
These drew on single cross-sectional [ 15, 16, 27, 28] and pre/post test cross-sectional design [ 18, 22], as well as focus groups [ 16, 23- 26].
Four studies were cross-sectional [ 11, 14, 20, 21].
Research designs included 1 case series and 21 observational studies comprising 4 cross-sectional, 5 case-control, and 12 cohort studies (Table 1).

Eighty-one out of 90 studies (90%) were cross-sectional, 5 (6%) were cohort studies, 2 (2%) were randomized controlled trials and 2 (2%) did not report the study design.
Three studies reporting data on early retirement were scored at low risk of bias (Table 3): two were cross-sectional (5, 7), and one was a cohort study (8).
Seventeen studies were cross-sectional (5, 7, 11, 13, 15, 16, 18, 20– 28, 28– 34), 4 were cohort studies (8, 17, 19, 23), 1 was a case-control study (35), and 1 study included cross-sectional and longitudinal analyses (6).
The USGA estimates roughly half of the 156-player U.S. Open field will come from the 13 sectional qualifiers, 11 in the United States and one each in Japan and England.
The most common study design was cross-sectional (7/15).
