Field trials evaluating the efficacy of porcine epidemic diarrhea vaccine, RNA (Harrisvaccine) in the Philippines.
Article in Tropical animal health and production, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Porcine epidemic diarrhea (PED) is a devastating enteric disease causing economic losses in many countries including the Philippines. To control PED, apart from oral administration of minced intestinal materials, there are still no effective control methods. The ability of porcine epidemic diarrhea vaccine RNA particle platform (PED-RP) to induce antibody in colostrum and milk samples was investigated in two pig herds with a differing PED status in the Philippines. Herd-A was naïve but herd-B was endemically infected with PED. Sera, colostrum, and milk samples were collected prior to and following vaccination, and assayed for the presence of antibody by viral neutralization (VN) and IgG and IgA levels by ELISA spike protein. The results from both herds, compared to the non-vaccinated control group, demonstrated significantly increased VN titers and IgG and IgA levels in colostrum and milk samples of sows at 0, 7, 14, and 21 days post parturition. Additionally, piglets from vaccinated sows had VN titers, and IgG and IgA levels are significantly higher than those from non-vaccinated sows. In conclusion, the results of the study demonstrate that PED-RP can be used to induce a satisfactory antibody response in colostrum and milk, as measured by VN titers and IgG and IgA levels.
