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
The Pathway to Planetary Health (PPH) is a theoretical framework that supports dietitians to undertake pro-environmental change within the food system.
aimTo explore the practical application and impact of the PPH.
methodsThe PPH was workshopped with dietitians and dietetic students (n = 46) using a mixed-methods case study approach. Data collection was embedded in workshop delivery via a (i) pre-post survey using both Likert scale and free-text responses, and (ii) qualitative explorations of participants' perspectives via interactive workshop activities. Analysis of quantitative data involved an independent samples t-test for normally distributed data and a Mann-Whitney U test for non-normally distributed data. Qualitative data were analysed thematically for survey responses and content analysis for workshop activity responses.
resultsParticipants increased their confidence to undertake pro-environmental change in their personal lives 4.1 ± 0.7 to 4.5 ± 0.8/5, and professional lives 3.6 ± 1.1 to 4.3 ± 0.9/5 (p < 0.05). Three themes were identified as barriers and enablers to pro-environmental action, including 'personal', 'social and professional' factors, as well as 'contextual and environmental' influences.
conclusionsThe application of the PPH framework was supported by workshop participants who significantly increased their confidence to undertake pro-environmental food system change.
