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
backgroundStaphylococcus (S.) spp. and Mammaliicoccus (M.) spp., in addition to their established role as components of the human and animal microbiota, can also cause opportunistic infections. This study aimed to characterize bacteria recovered from nasal cavities of healthy adult reindeer from two farms located in Poland (15 reindeer) and Germany (15 reindeer). The research include bacteria isolation, species identification, detection of selected superantigen (SAg) genes, assessment of biofilm-forming capability in vitro, and evaluation of antimicrobial resistance.
resultsSeventy-four staphylococci and mammaliicocci from 14 different species were isolated from 30 nasal swabs, with one to four strains obtained from each reindeer. The most frequently identified species was S. equorum, followed by S. succinus, M. sciuri, S. xylosus, M. lentus, S. chromogenes, S. devriesei, M. vitulinus, S. auricularis, S. agnetis, S. edaphicus, S. petrasii, S. simulans, and S. warneri. A greater species diversity was observed among the reindeer from Poland compared to those from Germany. All isolated bacteria were coagulase negative and clumping factor negative and did not carry any of the 21 analyzed SAg genes. M. sciuri demonstrated the highest antimicrobial resistance (100%), followed by S. succinus (91%) and S. equorum (78%). Resistance to rifampicin was the most common (30% strains). Sixteen strains (22%) exhibited biofilm production at least 10% greater than the strong biofilm-forming S. aureus ATCC 6538.
conclusionsThis study reveals a significant knowledge gap regarding the nasal microbiota of reindeer. It contributes to our understanding of staphylococcal and mammaliicoccal biota of reindeer and underscores the necessity for monitoring of microbial populations to assess their health implications for both animals and humans, particularly concerning the zoonotic transmission of bacteria.
