Hypercholesterolemia screening. Does knowledge of blood cholesterol level affect dietary fat intake?
Trial report in Canadian family physician Medecin de famille canadien, 1998. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo assess whether knowing blood cholesterol test results influences people's intention to lower their dietary fat intake and to assess changes in diet after 3 months.
designRandomized clinical study.
settingTwo hospital-based family medicine centres.
participantsA total of 526 patients aged 18 to 65, without prior knowledge of their blood cholesterol levels, were recruited. Seventy did not appear for their appointments, and 37 did not meet study criteria, leaving 419 participants. From that group, 391 completed the study.
interventionsPatients submitted to cholesterol screening were randomly assigned to one of two groups, completing the study questionnaires either before (control group) or after (experimental group) being informed of their screening test results. All participants were called 3 months after transmission of test results to assess their dietary fat intake at that time.
main outcome measuresDifferences in intention to adopt a low-fat diet reported between the experimental and control groups and differences in dietary fat intake modification after 3 months between patients with normal and abnormal blood cholesterol test results.
resultsKnowledge of test results influenced patients' intentions to adopt low-fat diets (F1,417 = 5.4, P = .02). Patients reported lower mean dietary fat intake after 3 months than at baseline (P < .0001). The reduction was greater in patients with abnormal screening results (F2,388 = 3.6, P = .03).
conclusionsBeing informed of personal blood cholesterol levels effects an immediate change in eating habits that translates into reduced dietary fat intake.
