* This table must include the cardinal manifestations of differential diagnosis and the list of diseases must be prioritize based on mortality rate and  prevalences of the diseases. For example, if you want to write a differential diagnosis table for  heat stroke, sepsis, malignant hyperthermia, neuroleptic malignant syndrome, and serotonin syndrome first, you need to mention the cardinal manifestations for these conditions as, hyperthermia and altered mental status. Second, prioritize your list based on disease mortality or prevalence then, create the table. You can find the example [[Heat stroke differential diagnosis#Differentiating Heat stroke from other Diseases that may cause hyperthermia and altered mental status|here]].
