Trial reportPreventive medicine
A randomized feasibility trial of brief telephone counseling to increase fruit and vegetable intakes.
Trial report in Preventive medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00468156 (Implementation Intentions for Improving Fruit and Vegetable Intakes), which is not on this map. Cited by 8 papers, 2 of them syntheses that pooled it.
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.

Abstract
objectiveThis study examined the feasibility of eliciting dietary changes in subjects recruited from a diverse primary care setting in Michigan using a written, one-page plan, either alone or with telephone counseling.
methodsA total of 96 subjects were enrolled from 9/28/06 to 5/7/07 (49% minorities). Subjects were randomized into three groups. Group 1 received written materials. Group 2 received written materials plus a one-page form that asked them to make a specific daily plan for substituting one less nutritious food with two servings of fruits and vegetables. Group 3 received the written materials, the one-page form and telephone counseling from a dietitian.
resultsSubject retention was 76% for the 12-week study. Subjects in Groups 1, 2 and 3 changed their mean intakes of fruit and vegetables by 0.4, -0.7 and 1.4 servings/day, respectively. Participants in Group 3 lost an average of 0.73 kg, increased their perception of the importance of eating fruits and vegetables, and 63% increased their serum levels of carotenoids by 20% or more.
conclusionRecruitment through a primary care clinic was effective. Formulation of a written plan combined with telephone counseling appears to be promising for improving fruit and vegetable intakes and warrants more definitive study.
