1 · What the graph read from 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

objectiveTo compare a peer leader (PL) versus a community health worker (CHW) telephone outreach intervention in sustaining improvements in HbA1c over 12 months after a 6-month diabetes self-management education (DSME) program. RESEARCH DESIGN AND

methodsOne hundred and sixteen Latino adults with type 2 diabetes were recruited from a federally qualified health center and randomized to (1) a 6-month DSME program followed by 12 months of weekly group sessions delivered by PLs with telephone outreach to those unable to attend or (2) a 6-month DSME program followed by 12 months of monthly telephone outreach delivered by CHWs. The primary outcome was HbA1c. Secondary outcomes were cardiovascular disease risk factors, diabetes distress, and diabetes social support. Assessments were conducted at baseline, 6, 12, and 18 months.

resultsAfter DSME, the PL group achieved a reduction in mean HbA1c (8.2-7.5% or 66-58 mmol/mol, P < 0.0001) that was maintained at 18 months (-0.6% or -6.6 mmol/mol from baseline [P = 0.009]). The CHW group also showed a reduction in HbA1c (7.8 vs. 7.3% or 62 vs. 56 mmol/mol, P = 0.0004) post-6 month DSME; however, it was attenuated at 18 months (-0.3% or -3.3 mmol/mol from baseline, within-group P = 0.234). Only the PL group maintained improvements achieved in blood pressure at 18 months. At the 18-month follow-up, both groups maintained improvements in waist circumference, diabetes support, and diabetes distress, with no significant differences between groups.

conclusionsBoth low-cost maintenance programs led by either a PL or a CHW maintained improvements in key patient-reported diabetes outcomes, but the PL intervention may have additional benefit in sustaining clinical improvements beyond 12 months.
