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

BackgroundFood insecurity is a major public health concern in India because of the high prevalence of malnourishment. The COVID-19 pandemic-induced lockdowns caused widespread disruptions in food systems. However, limited empirical evidence on food insecurity trends among vulnerable populations have been available.ObjectivesWe utilised longitudinal data collected from the Household Air Pollution Intervention Network (HAPIN) study in Tamil Nadu, India, between January to September 2020, in order understand the impact of the COVID pandemic on household food insecurity (HFI) in rural households.MethodsWe performed repeat (n = 4) administrations of the Food Insecurity Experience Scale tool developed by the Food and Agricultural Organisation among households with pregnant or lactating mothers, enrolled in the HAPIN study (n = 676) to include pre-COVID lockdown, during lockdown, immediately after lockdown and post-COVID lockdown periods.ResultsThe overall prevalence of HFI during the pre-COVID lockdown was 4% with a sharp fivefold increase during the lockdown period. The HFI decreased to 17% in the immediately after lockdown period and stabilised at around 7% in the post-COVID lockdown period.ConclusionsHigh levels of food insecurity (even if transient) that was observed during lockdown periods of the COVID 19 pandemic in rural Tamil Nadu indicate the potential for increased health risks for pregnant women and lactating mothers in low-income households.
