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 the change in the perception of self-efficacy of Primary Health Care professionals to provide dietary advice using the Protocols based on the Brazilian Dietary Guidelines for Individual Dietary Advice, after completing a massive online open course (MOOC).
methodsUncontrolled community trial. The study population comprises degree-holding healthcare professionals working in Primary Health Care in 64 small municipalities in Brazil. The intervention was a massive online open course. The outcome was assessed by a validated scale that measures the perception of self-efficacy to provide dietary advice based on the Protocols based on the Brazilian Dietary Guidelines. The mean score was calculated before and after the intervention and the change in score was tested with paired t-test (p-value<0.05).
resultsAmong the 1,201 health professionals, the average self-efficacy score increased from 23.71 to 37.31 after the intervention (p-value<0.001), an increase that was significant in all professional categories.
conclusionThe massive online open course increased the perception of self-efficacy of Primary Health Care professionals to provide individual dietary advice based on the Protocols based on the Brazilian Dietary Guidelines.
