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
Background and Aim: Non-adherence to diabetes medication treatment is a recognized public health problem that can lead to unfavorable clinical, humanistic, and economic outcomes. This study aimed to analyze adherence to insulin treatment in people with type 1 diabetes or type 2 diabetes in primary health care in a Brazilian municipality. Methods: This cross-sectional study was developed with 152 participants and a simple probability sample. We collected blood and urine samples, performed ophthalmological fundus examinations using a portable retinal camera on a smartphone, and conducted face-to-face interviews. Adherence was measured using the Insulin Treatment Adherence Measure, a version validated in Brazil. Results: A higher proportion of women (63.2%), without private health plan (84.2%), with a medically diagnosed type 2 diabetes (93.3%), inadequate glycemic control (76.9%), and without diabetic retinopathy (71.7%) was observed. The prevalence of insulin therapy adherence was estimated at 47.4% (95% CI 39.4-55.3). Higher insulin therapy adherence was observed among males, self-reported Nonwhite race/ethnicity, and those diagnosed with systemic arterial hypertension. A negative association was observed with alcohol abuse, amputation, and among those with private health plan ( Conclusion: Adherence to insulin treatment was low, and this scenario can lead to complications with various impacts, including increased healthcare costs. The associated variables evidenced the need for drug therapy management, incorporating multidimensional care for people with diabetes, to enable disease control in primary health care.
