Risk Factors for and Prevalence of Failure of Passive Transfer of Immunity in Calves on Dairy Farms in Türkiye.

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
backgroundFailure of passive transfer of immunity (FPTI) is perhaps the most important factor in the health of neonatal calves. Given the variation between countries in FPTI, national data need to be documented to add to the international database for future meta-analyses.
objectivesThe aim of this study was to evaluate the prevalence of and risk factors for FPTI in dairy herds in Türkiye.
methodsBlood serum samples from 1026 calves in 76 dairy herds in 16 provinces of Türkiye were analysed using a digital Brix refractometer to assess FPTI, defined as a Brix value < 8.5%. Data on risk factors were collected during farm visits to sample calves. Herd size was categorised based on the number of lactating cows: Group I (≤ 20), Group II (21-100), Group III (101-200), Group IV (201-300), Group V (301-500), Group VI (501-1000) and Group VII (> 1000).
resultsFPTI incidence was 22.4% overall. Significant factors associated with FPTI included small herd size (p = 0.002), lower dam parity (p = 0.005), breed of calves (p < 0.001), natural sucking of colostrum (p = 0.003) and birth in summer or winter (p = 0.005).
conclusionThe prevalence of FPTI in Turkish dairy herds was within international norms but higher than recently recommended consensus prevalence. This research shows that there were both modifiable and non-modifiable significant risk factors for FPTI in Turkish dairy herds, specifically colostrum feeding method and season of birth and herd size, dam parity and calf breed.
