摘要

Authors’ Response: We appreciate Dr Binney’s letter to the editor regarding our study, “Relationship Between Pitching a Complete Game and Spending Time on the Disabled List for Major League Baseball Pitchers,” ~( 1 ) as it provides us with the opportunity to clarify our manuscript. First, our hypothesis did not mention a 9-inning game. A complete game indicates that the pitcher threw every inning in the game, which can be &9 innings, without having anyone relieve him. It is a simple point but one that should be recognized. As Dr Binney points out, within our study, an insufficient number of controls were available for the entirety of the complete game/disabled list (CG/DL) group; thus, only those CG/DL patients with an available control were included. This matching was performed on the basis of innings pitched, to control for workload. While Dr Binney suggests that doing so created a selection bias within the CG/DL group, this selection bias was purposeful, as it controls for workload; that is, increased workload can create increased DL risk. Failure to control for this variable would leave residual confounding between groups that could influence our comparison. While it did prevent us from using the full study group, which reduced our sample size, answering our question required this compromise to be made and was acknowledged within the limitations of the study. Dr Binney also suggests that we selected a control group based on the dependent variable because the CG group would tend to pitch deeper into games. However, the majority of the CG pitchers (78%) threw only 1 CG per season. Thus, given that a CG is a rare occurrence—even for those who managed to pitch a CG—the actual influence of this issue on our analysis is minimal. The remainder of Dr Binney’s concerns can be addressed by elaborating on our manuscript. Specifically, we compared pitcher-seasons with pitcher-seasons, as discussed within the last paragraph of the Results section, in which the index year for controls and the comparative year in the CG group were compared. Thus, the 20% and 74% were for the index year in the controls and the index year in the CG group, respectively; that is, pitcher-seasons were compared with pitcher-seasons, and 1-year risk was compared with 1-year risk. As mentioned in the Discussion section, the main finding from this study was not that CG players are more likely to be on the DL; the main finding was that higher-volume pitchers are more likely to spend time on the DL than lower-volume pitchers and that further work is required to determine whether an inning threshold exists where pitchers are more likely to sustain an injury and spend time on the DL. Thus, we agree that “baseball organizations should not use this study as evidence that throwing a CG places pitchers at greater risk for injury.” We instead respectfully suggest that the findings of retrospective database studies are useful for hypothesis generation in subsequent prospective clinical studies, the findings of which can then change practice. We appreciate the author’s comments and the opportunity to clarify these points. Brandon J. Erickson, MD New York, New York, USA Peter N. Chalmers, MD Salt Lake City, Utah, USA Anthony A.

机译：作者的回应：我们感谢Binney博士写给我们的信，内容涉及我们的研究“大联盟投手投出完整比赛与残疾人名单上的花费时间之间的关系”〜（1），因为它为我们提供了澄清的机会我们的手稿。首先，我们的假设没有提到9局游戏。一场完整的比赛表明投手投掷了比赛中的每一局，可能是＞ 9局，而没有任何人释放他。这是一个简单的观点，但应该认识到这一点。正如宾尼博士所指出的那样，在我们的研究中，没有足够数量的控件可用于整个游戏/残疾清单（CG / DL）组。因此，仅包括那些有可用对照的CG / DL患者。这种匹配是根据局调进行的，以控制工作量。 Binney博士建议这样做会在CG / DL组内造成选择偏见，但这种选择偏见是有目的的，因为它可以控制工作量。也就是说，增加的工作量会增加DL风险。无法控制此变量将在组之间留下残余的混淆，这可能会影响我们的比较。虽然这确实使我们无法使用整个研究组，从而减少了样本量，但要回答我们的问题仍需做出折衷方案，并在研究范围内得到认可。 Binney博士还建议我们根据因变量选择一个对照组，因为CG组倾向于更深入地参与游戏。但是，大多数CG投手（78％）每个赛季只投掷1 CG。因此，鉴于CG很少发生，即使对于那些成功尝试CG的人来说，此问题对我们分析的实际影响也很小。 Binney博士所关注的其余问题可以通过详细阐述我们的手稿来解决。具体来说，我们将“投手季节”与“投手季节”进行了比较，如“结果”部分的最后一段所述，其中比较了CG组的对照组的指数年和比较年。因此，对照组的指标年和CG组的指标年分别为20％和74％。也就是说，将投手季节与投手季节进行比较，并将1年风险与1年风险进行比较。如“讨论”部分所述，此研究的主要发现不是CG播放器更可能位于DL上。主要发现是，高容量的投手比低容量的投手更有可能在DL上花费时间，还需要进一步的工作来确定是否存在局限性阈值，从而使投手更容易遭受伤害并花时间在DL。因此，我们同意“棒球组织不应以这项研究为证据，证明投掷CG会使投手受伤的风险更大。”相反，我们恭敬地建议，回顾性数据库研究的结果可用于随后的前瞻性临床研究中的假设生成，其发现随后可改变实践。我们感谢作者的评论以及有机会澄清这些问题。布兰登·J·埃里克森，医学博士美国纽约，纽约州Peter N.
