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
Purpose: This study investigated the acute effects of green and blue environment exposure combined with Tai Chi exercise on the short-term emotions of elderly males, and comparatively analyzed the characteristics of acute emotional responses to short-term exposure to different environment types paired with Tai Chi exercise, as well as differences in the maintenance of acute emotional effects following subsequent exposure to different environments after the combined intervention. Methods: Elderly males from Qinlou Subdistrict, Donggang District, Rizhao City, Shandong Province were recruited and assigned to four groups using the random number table method: conventional environment + Tai Chi (TJQ, Results: Compared with baseline, the GTJQ, BTJQ, and GBTJQ groups exhibited positive changes in HRV, blood pressure, and emotional indices after 20-min environmental viewing. All of the groups (TJQ, GTJQ, BTJQ, and GBTJQ) demonstrated positive changes in these parameters immediately after acute exercise and at heart rate recovery to resting level. The magnitude of acute positive emotional changes across all of the time points followed the order: BTJQ > GBTJQ > GTJQ > TJQ, with the BTJQ group showing the most pronounced changes. Conclusion: Acute exposure to different types of green and blue environments exerts positive effects on the short-term emotional health of elderly males. On this basis, acute exposure to different green and blue environments in combination with Tai Chi exercise further enhances short-term emotional outcomes in elderly males. Further, following this combined acute effect, continuous exposure to different green and blue environments maintains positive emotional changes for a longer duration during the recovery period. The environment types, ranked by the magnitude of acute positive changes and maintenance effects, are as follows: blue environment > balanced green-blue environment > green environment > conventional environment.
