Impacts on performance of growing-finishing pigs under heat stress conditions: a meta-analysis.
Synthesis in Veterinary research communications, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 23 papers, 2 of them syntheses that pooled 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.
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
High ambient temperatures are a challenge for animal production around the world, and they are one of the major reasons for economic and productive losses in pig production. Under stress conditions, the energy contribution to productive functions is reduced, generating health imbalances, decreased productivity rates and changes in animal behavior. Despite the numerous articles published on this subject, the variability of results on performance parameters is high. For this reason, the objective of the present study was to evaluate the actual impact of high ambient temperature (HAT) (29 °C to 35 °C) on growing-finishing pig performance, compared with animals kept in a thermoneutral environment (TNT) (18 °C to 25 °C), based on meta-analysis. Data on average daily gain (ADG), average daily feed intake (FI) and feed gain ratio (F:G) were extracted from 22 (n = 22) papers published in scientific journals. The values were analyzed using an expansion of the t-test, considering the random effect of each study. Results showed that HAT reduced the values of ADG (654.38 vs 595.81 g/d) and FI (2.141 vs 1.875 g/d) when compared with the thermoneutral group. There was no statistical difference between the F:G values for both groups. In conclusion, high ambient temperatures negatively influence performance parameters of growing-finishing pigs when compared with those in thermoneutral conditions.
