Perceived climate change impacts on food security in coastal communities of Puerto Princesa City, Philippines.

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
The Philippines is one of the most vulnerable archipelagic low-middle-income countries in regard to the impacts of climate change. Consequently, Puerto Princesa City, a coastal city in central Palawan, Philippines, faces the challenges of these impacts, which affect the food security of its coastal communities. This research presents an assessment of perceived climate changes and investigates their impact on food security. The research employed descriptive analysis to assess the perception of the residents towards climate change and its impacts, and multiple linear regression to examine the connections between climate change indicators and the fundamental components of food security within coastal communities. The results revealed that most participants (94%) believe climate change is happening, and many (71%) acknowledged this as anthropogenic. There are observations of sea level rise (76%), wave intensity (69%), warmer sea surface temperature (73%), and more frequent and stronger rainfall (72%) in comparison to 10 years ago. Coastal communities have become less food secure. Sea level rise was significantly associated with decreased food availability, access and stability (
