postpoliomyelitis syndrome: Postpoliomyelitis syndrome (PPS) is a neurologic disorder characterized by the development of new neuromuscular symptoms such as progressive muscular weakness or abnormal muscle fatigability occurring in survivors of the acute paralytic form of poliomyelitis (see this term), 15-40 years after recovery from the disease, and that is unexplained by other medical causes. Other manifestations that can occur gradually include generalized fatigue, muscle atrophy, muscle and joint pain, intolerance to cold, and difficulties sleeping, swallowing or breathing.

CodeWAS (R11)
↥CodeWAS is a tool for exploring the associations between an endpoint and all of the medical codes and drug codes.
This is a new tool, please reach out using the contact form for feedback and improvement ideas.
First, a cohort is built by matching controls to the endpoint cases using year of birth and sex. Then, a Fisher test is done for all the medical codes and drug codes between the cases and controls of this cohort. Codes are reported in the table below if they have −log10(p-value) ≥ 6.
