The rationale is stated but the link to spatial or tactical analysis is incomplete. No clear rationale is provided. Q3 Objectives The study objective or research question is clearly stated. The objective is stated but lacks detail or direct connection to the analysis. No clear objective is reported. Q4 Study design The study design or analytical approach is clearly identifiable. The design or approach is implied but not fully described. The design cannot be determined. Q5 Setting and competition context The competition level, setting, and relevant match context are clearly reported. Some context is provided, but key details are missing. The setting or competition context is unclear. Q6 Participants or sample The players, teams, games, possessions, shots, or events analyzed are clearly described.

Outcome data are not reported. Q16 Main results Main findings are clearly reported in relation to the stated indicators or questions. Main results are reported but lack detail or clear linkage. Main results are not clearly reported. Q17 Additional analyses Additional or subgroup analyses, where used, are clearly reported. Additional analyses are mentioned but incompletely described. Additional analyses are not reported or are unclear. Q18 Key results Key results are summarized in relation to the study objectives. Key results are presented but their relation to the objective is incomplete. Key results are not clearly summarized. Q19 Limitations Study limitations are clearly reported and linked to data, methods, indicators, or interpretation. Limitations are mentioned only generally. Limitations are not reported. Q20 Interpretation The interpretation is clearly linked to the reported results and basketball context. Interpretation is provided but the link to results or context is incomplete.
