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

The objectives of this study are to analyze the market response by: (a) examining the consequences of the domestic market obligation (DMO) on coal prices policy on the difference in abnormal return (AR) prior to and after the announcement; (b) determine the effect of DMO policy announcements on coal prices on trading volume activity (TVA). This research examined daily stock returns on the shares of 19 coal companies listed on the Stock Exchange in 2018, ten days before and after the DMO announcement (February 23 to March 23, 2018). Statistical analysis was used to calculate the average abnormal return (AAR) and trading volume activity (TVA). The results showed that the announcement of domestic market obligation (DMO) received a negative response from the market. This study also found that the abnormal return was negative eight days before the DMO announcement. This study also finds the cause of overreaction in the short term, namely a significant price reversal process immediately after the announcement of the DMO. The paired sample
