The cross -sectional design did not allow causation or changes over time in pain-related impairment of TMD patients with chronic pain.
The cross-sectional design did not allow causation or changes over time in patients' HRQOL to be studied.
The cross-sectional design did not allow causation or changes over time in patients' QOL to be studied.
In contrast, chronic illness is typically characterized by gradual onset, lengthy or indefinite duration, multivariate causation (which may change over time), and a focus on functional status rather than individual diagnoses.
When we reason about change over time, causation provides an implicit preference: we prefer sequences of world states in which one world state leads causally to the next, rather than sequences in which one world state follows another at random and without causal connections.
First, it was a cross sectional study and therefore, we were unable to draw conclusions about causation and make observations over time.
Because there are many unobserved characteristics that also change over time, inferring causation from correlated trends is problematic.
Secondly, although we have clearly demonstrated an increase in nodal harvest in the audit and feedback health district, more marked over time, true causation cannot be proven in such a study design.
