Analyze chronic trends
Interpret bloodwork trends against normal ranges with a CER and evaluate data limits.
CER arguing whether the simulated patient's chronic condition is improving or worsening, using the Wednesday time-series graph as evidence and explaining why the trend is more informative than a single reading.

Vetted sources picked for today's question. Skim these before you take a position or start the work, so your argument and evidence are grounded.
- CER:
- Claim, Evidence, Reasoning — make a claim, back it with evidence, explain your reasoning.
- SOP:
- Standard Operating Procedure — the exact steps to follow (especially in a lab).
- Tracker:
- Your PLTW progress log where you record completed evidence.
- myPLTW:
- The PLTW course site where you do the online activities — you open it through Schoology.

💡 Big idea: Trend analysis transforms a column of numbers into a clinical narrative about whether a patient is getting better, worse, or staying stable.
- 0:00Return Wednesday graphs; as a class, describe the trend for one marker using direction, rate, and range relationship
- 0:12Students describe the trend for their chosen marker in their own words in the notebook
- 0:22CER writing: claim (improving or worsening), evidence (specific trend description with data points), reasoning (why trend beats a single reading)
- 0:48Identify two variables that could affect the marker (e.g., diet, exercise, medication compliance)
- 1:02State one limitation of wearable or self-reported data for chronic-disease monitoring
- 1:10Pair-share CERs; preview Friday submission
- • You graphed the data yesterday. Today you read the story it tells. Is this patient's glucose going up, down, or staying the same? Are they responding to treatment, or is their condition worsening?
- • We are going to practice describing a trend: direction, rate, and relationship to the normal range boundary. These are the three things a clinician says when they look at a patient's longitudinal data.
- • Then you will write a CER arguing whether this patient's chronic condition is improving or worsening. Your evidence is the graph. Your reasoning explains why the trend, not any single reading, is the real evidence.
- • We will end by discussing the limitation of wearable and self-reported data, which is increasingly common in chronic-disease monitoring but has its own accuracy problems.
- 1Compare each marker's trend to its normal range over time.
- 2Write a CER: is this patient's chronic condition improving or worsening?
- 3Explain how a single reading could mislead vs. a trend.
- 4Identify two variables that could affect a blood marker.
- 5State one limitation of wearable or self-reported data.
- • I can interpret longitudinal trends against ranges.
- • I can explain why trends beat single readings.
- • A trend is described by its direction (increasing, decreasing, stable), rate of change (gradual vs. rapid), and relationship to the normal range boundary.
- • A single high reading might reflect a bad day, a recent meal, or lab error; a trend of consistently elevated readings over six months indicates a chronic condition.
- • Two variables that commonly affect blood glucose are diet and exercise in the 24 hours before the test; cholesterol is affected by fasting status at the time of the draw.

Day 4 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: In myPLTW, complete the Lesson 2.1 Talk to Your Doc clinical-data trend-analysis reflection in the lab activity.
Mark the Lesson 2.1 trend-analysis reflection complete in myPLTW.
You graphed the data Wednesday. By the end of today your CER and the trend description should both be done.
Completed CER with trend description and at least one data point cited as evidence.
