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 our study, we explore the relationship between the New Cooperative Medical Scheme (NCMS) - a significant health insurance expansion in rural China - and healthcare supply, utilizing a nationwide dataset spanning from 2004 to 2011. Our findings reveal notable positive supply-side responses to the NCMS insurance expansion, characterized primarily by a substantial increase in the number of inpatient beds at township health centers serving rural residents. Moreover, we estimate large increases in the number of county hospitals; however, these effects lack statistical significance. These findings indicate that the surge in demand prompted by NCMS enrollment gain is associated with greater healthcare investment by existing rural providers rather than encouraging new providers to enter the market. Furthermore, when adjusting for these supply-side responses, we find that responsive healthcare supply plays a crucial role in mediating the effectiveness of the NCMS: the growth in inpatient care utilization following the NCMS is significantly mitigated once the availability of inpatient beds is controlled. These insights underscore the universal importance of responsive healthcare supply in the effectiveness of public insurance expansions.
