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.

2 · The registry

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

objectiveLatinos with type 2 diabetes (T2D) face major healthcare access and disease management disparities. We examined the impact of the Diabetes Among Latinos Best Practices Trial (DIALBEST), a community health worker (CHW)-led structured intervention for improving glycemic control among Latinos with T2D. RESEARCH DESIGN AND

methodsA total of 211 adult Latinos with poorly controlled T2D were randomly assigned to a standard of healthcare (n = 106) or CHW (n = 105) group. The CHW intervention comprised 17 individual sessions delivered at home by CHWs over a 12-month period. Sessions addressed T2D complications, healthy lifestyles, nutrition, healthy food choices and diet for diabetes, blood glucose self-monitoring, and medication adherence. Demographic, socioeconomic, lifestyle, anthropometric, and biomarker (HbA1c, fasting blood glucose, and lipid profile) data were collected at baseline and 3, 6, 12, and 18 months (6 months postintervention). Groups were equivalent at baseline.

resultsParticipants had high HbA1c at baseline (mean 9.58% [81.2 mmol/mol]). Relative to participants in the control group, CHWs had a positive impact on net HbA1c improvements at 3 months (-0.42% [-4.62 mmol/mol]), 6 months (-0.47% [-5.10 mmol/mol]), 12 months (-0.57% [-6.18 mmol/mol]), and 18 months (-0.55% [-6.01 mmol/mol]). The overall repeated-measures group effect was statistically significant (mean difference -0.51% [-5.57 mmol/mol], 95% CI -0.83, -0.19% [-9.11, -2.03 mmol/mol], P = 0.002). CHWs had an overall significant effect on fasting glucose concentration that was more pronounced at the 12- and 18-month visits. There was no significant effect on blood lipid levels, hypertension, and weight.

conclusionsDIALBEST is an effective intervention for improving blood glucose control among Latinos with T2D.
