Description

CROSS-REFERENCE TO RELATED APPLICATIONS The entire disclosure of Japanese Patent Application No. 2022-095661 filed on Jun. 14, 2022 is incorporated herein by reference. BACKGROUND Technical Field The present invention relates to a recording medium, an information processing apparatus, an information processing system, and an information processing method. Description of Related Art In recent years, a diagnosis support (CAD: Computer Aided Detection/Diagnosis) system has been put into practical use in which a medical image is analyzed using a computer, a lesion detection region detected by the image analysis is presented to a doctor, and the doctor is asked to make a determination. For example, Japanese Patent No. 4651353 discloses that an annotation is added to a lesion detection region detected by CAD. Recently, a system capable of detecting a lesion candidate region in an image by performing computer processing such as ArtificialIntelligence (AI) analysis based on machine learning or a deep learning technique on a medical image has also been proposed. There are many false positives in a lesion detection region detected by computer processing such as CAD and AI. Therefore, a doctor determines whether or not the lesion detection region detected by the computer is false positive. However, when the computer detects a lesion in a new image of the same patient, the computer may also detect and display a region corresponding to a lesion detection region determined to be false positive in the previous image by the doctor as a lesion detection region. Therefore, for example, a skilled case of a skilled doctor or a doctor who has interpreted last time, since false positive result is displayed again, the doctor may feel annoyed. Furthermore, in a case of an unskilled doctor or a doctor who has not interpreted last time, there is also a risk that false positive will be overlooked. SUMMARY One or more embodiments of the present invention provide a technological improvement over such conventional technologies as discussed above. In particular, one or more embodiments of the present invention provide a recording medium, an information processing apparatus, an information processing system, and an information processing method that enable a user to recognize false positive region among lesion detection regions obtained by computer processing. This provides a practical, technological improvement over conventional technologies that would be readily appreciated by those skilled in the art, as will be discussed in further detail later. According to an aspect of the present invention, there is provided a non-transitory computer-readable recording medium storing instructions causing a computer to execute: first acquiring that is acquiring information on whether each of a lesion detection region (i.e., one or more first lesion detection regions) input by a user with respect to a first analysis result including at least one lesion detection region obtained by computer processing on a first medical image of a patient is false positive; second acquiring that is acquiring a second analysis result including at least one lesion detection region (i.e., one or more second lesion detection regions) obtained by computer processing on a second medical image of the patient; and displaying that is displaying a first region (i.e., false correspondence region) among the lesion detection region obtained by the second acquiring in a display manner different from a display manner of a second region (i.e., non-false correspondence region), the first region being a region corresponding to a lesion detection region included in the first analysis result for which information indicating that the lesion detection region is false positive is acquired by the first acquiring, and the second region being a region corresponding to a lesion detection region included in the first analysis result for which information indicating that the lesion detection region is not false positive is acquired by the first acquiring. According to an aspect of the present invention, there is provided an information processing apparatus comprising a hardware processor that: acquires information on whether each of a lesion detection region (i.e., one or more first lesion detection regions) input by a user with respect to a first analysis result including at least one lesion detection region obtained by computer processing on a first medical image of a patient is false positive; acquires a second analysis result including at least one lesion detection region (i.e., one or more second lesion detection regions) obtained by computer processing on a second medical image of the patient; and displays a first region (i.e., false correspondence region) among the lesion detection region included in the second analysis result in a display manner different from a display manner of a second region (i.e., non-false correspondence region), the first region being a region corresponding to a le
