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

Having developed rapidly for more than 40 years of reform and opening up, the supply of the urban land in the Pearl River Delta urban agglomeration (PRDUA) has been increasingly tense. Based on a panel data set for the period 2006-2021, this paper applied a super-efficiency epsilon-based measure (EBM) model with undesirable outputs to calculate the urban land utilization eco-efficiency (ULUEE) of nine cities in the PRDUA, subsequently using a Tobit model to analyze the influencing factors of ULUEE. The results show that: (1) ULUEE in the PRDUA during the study period presents a fluctuating character over time. (2) ULUEE was at a higher level around Guangzhou, Shenzhen, and Foshan, while ULUEE in Zhuhai, Zhongshan, Jiangmen, and Dongguan was lower. (3) Economic development, and opening up to the outside world had positive impacts on ULUEE, while government intervention and infrastructure construction had a negative impact on ULUEE.
