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

Objective: Front-of-pack labeling (FOPL) was implemented in Peru as a national prevention strategy, but little is known about its evaluation, impact, or effectiveness in nutrition and health. This scoping review shows the evidence on front-of-pack warning labels and nutrition and health variables in Peru. Methods: The search was conducted (September 2024 and June 2025) through electronic databases (MEDLINE, SciELO, CAB abstracts, FSTA, Scopus) and gray literature (VHL Regional Portal, ProQuest) on any FOPL study (any study design and setting) in Peru, complemented by a hand search of local theses. Results: In total, 287 records were identified and 55 studies were included (15 peer-reviewed and 40 theses). Most studies were cross-sectional surveys among adults in Lima on FOPL awareness, attitudes, knowledge, purchase intention, and food consumption. A majority of studies reporting on attitudes ( Conclusion: This review generally found high FOPL awareness and perceptions. Half of the studies showed a strong understanding and use of FOPL for purchasing decisions, and reported no change in the consumption of FOPL products in adults from Lima. More studies with stronger designs are needed to better understand the impact of FOPL on health outcomes.
