Seven sources, one grid: a composite evidence table on IV replacement timing, carrying levels, quality grades and a closing synthesis, as NU325 often asks in Unit 7. Searches like "nu 325 unit 7 assignment example", "nu325 unit 7 sample" and "nu325 unit 7 example" land here.
What a finished NU325 Unit 7 evidence table looks like
A wide table set sideways across two or three pages, followed by a synthesis of about 400 words. Columns run: citation, purpose, design, sample and setting, intervention and comparison, outcome measures, key findings, limitations, Johns Hopkins level and quality, and relevance to the PICOT question. Seven rows follow, each a composite with bracketed citation details: two randomized trials including the Unit 5 study, a systematic review with meta-analysis, a prospective cohort of dwell time and phlebitis, a cost analysis, the Unit 6 phenomenological study, and a national guideline. Findings cells carry numbers with confidence intervals where the source reports them. A short key explains abbreviations such as VIP and CRBSI. The synthesis beneath groups what agrees, what conflicts and what is missing, and ends on one sentence rating the overall strength of evidence.
How a NU325 Unit 7 example is structured
The table is designed to be read in both directions. Across a row, each source is summarized tightly enough to compare with any other; down a column, patterns appear that no single article shows. Cells hold fragments rather than sentences, which keeps the grid readable, and every number carries its unit. Rows are ordered by level of evidence, highest first, so the reader meets the strongest sources before the weaker ones. The limitations column is filled for every row, the guideline included. The synthesis does work the grid cannot: it notes that five sources point the same way on phlebitis, that bloodstream infections were too rare in any single trial to compare, that phlebitis was defined three different ways, and that only the qualitative study asked patients anything. A strength-of-evidence statement tied to the question closes it.
Columns chosen for comparison
Ten columns cover what a reader needs to weigh one source against another, from design through relevance. Nothing in the grid appears only for completeness.
Rows ordered by level
Randomized trials and the review sit at the top, the cohort and qualitative study in the middle, the guideline and cost analysis below. The order shows at a glance where the weight of evidence lies.
Numbers with their uncertainty
Findings cells report effect sizes with confidence intervals wherever a source gives them. A difference shown without its interval would hide exactly what the noninferiority question depends on.
Three definitions of one outcome
Sources defined phlebitis by a VIP score of two or more, by a different five-point scale, or by clinician judgment. The synthesis names that spread as a limit on how directly the results compare.
What the grid cannot show
Bloodstream infections were too few for any trial to compare arms with confidence, and only one source asked patients about their experience. The synthesis states both gaps plainly.
Where marks go in NU325 Unit 7
Evidence tables in this unit most often fall short by copying abstract sentences into cells, which fills the grid without comparing anything. A table with no synthesis beneath it hands the analysis back to the grader. Limitations missing for some rows, usually the ones that support the writer's view, suggest selective reading. Levels assigned inconsistently, a cohort at Level II in one row and Level III in the next, cost accuracy points, as does a scheme that is never named. Findings without numbers, or numbers without units, cannot be compared. Rows that include sources outside the PICOT population, such as central line studies, blur the answer. Synthesis paragraphs that describe sources one by one repeat the table rather than reading across it.
Get a NU325 Unit 7 example written to your instructions
Tables differ by section: some templates fix the columns, some ask for a synthesis matrix, and some want a narrative beneath. Forward the Unit 7 template or instructions, the rubric and the studies appraised so far; every cell of the returned table is drawn from those sources, with a synthesis reading across them.

NU325 Unit 7 questions, answered
What goes in the relevance column of an evidence table?
A brief judgment of how closely the source matches your PICOT question: whether its population, intervention, comparison and outcomes resemble yours, and what that means for using it. A strong trial in a different population may deserve less weight than a weaker study on patients like yours. One or two lines per row is usually enough for that column.
Should a guideline appear in an evidence table?
Often yes, if your instructions allow non-research evidence. In the Johns Hopkins scheme, clinical practice guidelines sit at Level IV, below research, and they should be labeled as guidelines rather than studies. Note the year, since guidelines age, and whether the recommendation you cite is rated strong, weak or unresolved by its own authors.
How long should the synthesis beneath the table be?
Follow the prompt, though a few hundred words is common. The synthesis should say what the sources agree on, where they conflict and why, what is missing, and how strong the evidence is overall. It should not walk through each row again. If the synthesis could be rebuilt by reading the rows aloud, it has not yet synthesized anything.
