A Simple Measure of Catastrophic Health Expenditures.
Article in Health economics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
In this paper, we propose a simple Watts-type measure of catastrophic health expenditure (CHE) which is an adaptation of the classic Watts poverty measure. The appeal of the proposed measure stems from the fact that it is both additively decomposable (i.e., it provides information on the contributions of the various population subgroups of interest, e.g., as categorized by gender, race, region, etc., to the overall level of CHE), and multiplicatively decomposable (i.e., it enables identification of three key drivers of CHE, namely, CHE incidence, CHE intensity and CHE inequality). We also describe how the Watts-type CHE measure can be estimated and additively decomposed using the widely available ordinary least squares regression packages. The empirical example provided shows the policy value of the Watts-type CHE measure, which makes it a useful supplement to the Foster-Greer-Thorbecke type measures of CHE recently proposed by Ogwang and Mwabu. Temporal dynamics in the Watts-type CHE measures are also introduced.
