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

backgroundThis study investigates the crowding-out effect of out-of-pocket (OOP) health expenditures for non-communicable diseases (NCDs) on household consumption in Nigeria, a critical issue in sub-Saharan Africa (SSA) given the escalating prevalence of NCDs and associated high care costs.

methodsUsing data from the 2018/2019 Nigerian Living Standard Survey, we employ a Generalised Method of Moments estimator and conditional Engel curve equations derived from the Quadratic Almost Ideal Demand System to analyse the impact of NCD and non-NCD OOP expenditures on 13 household consumption categories.

resultsDespite representing <2% of household budgets, NCD OOP expenditures significantly crowded out essential spending, particularly on healthier food options (fruits, vegetables, protein) and cooking energy sources, disproportionately affecting lower-income households. Intriguingly, discretionary spending on sugar, alcoholic/sugary beverages, entertainment (including tobacco) and meals outside the home remained unaffected, possibly indicating reliance on these fast meal alternatives due to limited cooking fuel access. Middle-income households also experienced crowding out of staples and education expenditures.

conclusionsThese findings highlight the urgent need for universal health coverage to reduce OOP burdens, alongside targeted interventions addressing NCD burden, dietary quality, the energy crisis and health inequities in Nigeria and, by extension, SSA.
