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
purposeThe present study deals with a redescription of the copepod Lernaeenicus longiventris Wilson, 1917 (Copepoda: Siphonostomatoida: Pennellidae) found on the Pacific crevalle jack Caranx caninus Günther, using morphological and molecular analyses.
methodsFish were collected off Mazatlán Port (23° 12' N, 106° 26' W), in the State of Sinaloa, Mexico (southeastern Gulf of California). The copepods were morphologically analyzed by light microscopy. Sequences of the COI mtDNA gene were generated for the first time for this species. These sequences were compared to COI sequences from six species of Lernaeenicus available in GenBank.
resultsThe specimens of the present study exhibited a cephalosome without apparent lateral processes, which were originally described for L. longiventris. No remarkable differences were observed with previous descriptions regarding appendages and body proportions. The phylogenetic tree based on COI sequences showed that L. longiventris was closer to L. radiatus although with low bootstrap values support in ML tree, both species formed a sister clade of L. sprattae.
conclusionsLernaeenicus longiventris is the unique species of the genus in the Mexican Pacific and the Gulf of California, and also the unique species of Lernaeenicus infecting C. caninus. Molecular data of L. longiventris from host and locality type are required to avoid misidentification of this species.
