Snapshots of food security status in Western Sydney post-COVID-19 lockdown: a cross-sectional study.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThe COVID-19 lockdown had significant effects on daily life, particularly food security among Australian adults. This study examined the longer-term impact of lockdown measures on food security in Western Sydney, a region more socio-economically challenged within the Sydney area.
methodsA total of 548 adults were recruited via convenience sampling at least 6 months post-lockdown (May-August 2022 and January-February 2023). Of these, 523 completed the validated six-item USDA Household Food Security Survey Module and were included in the quantitative analysis. Fifty-four participants took part in 12 focus group discussions (FGDs), including some participants who did not complete the survey. FGDs explored food security perceptions based on its four pillars, both during and after lockdown. Inductive thematic analysis was conducted manually in Excel and verified in NVivo (version 14.23.0).
resultsThe mean age of survey participants (n = 523) was 25.1 ± 9.7 years, and 63% were women. Among participants with available birthplace data (n = 521), 267 were Australian-born and 254 were overseas-born; birthplace information was missing for two participants. Only 6% reported improved food security post-lockdown. Using the USDA tool, females were significantly more likely than males to report meal size reductions post-lockdown (p = 0.0001)> FGDs revealed that food availability, access, utilisation and stability were affected by rising food prices, fear of virus contamination and shifts in shopping habits during and after lockdown.
conclusionWhile the measured food insecurity prevalence was low based on the survey findings, the qualitative findings indicated that some participants continued to experience disruptions or vulnerabilities related to food security at least 6 to 15 months post-lockdown. These findings highlight the need for both crisis-responsive and recovery-oriented food security policies, with particular attention to supporting adult women who appear disproportionately affected.
