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
To assess the early predictive value of maternal parameters for early-onset sepsis (EOS) in preterm infants, especially including the maternal neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV). The retrospective cohort study examined a total of 231 preterm infants (69 with EOS) from May 2017 to October 2021 of the Fourth Hospital of Hebei Medical University, randomly divided (7:3) into the training set group (n = 162) and validation set group (n = 69). Thirteen clinical variables (including MPV, NLR, and PLR) were included as the research objects. By logistic regression, the factors significantly associated with EOS were distinguished. Additionally, a nomogram was constructed based on the independent risk factors, the validation of which relied on the concordance index, calibration curves, receiver operating characteristic curves, and decision curve analyses. Multivariate logistic regression proved that NLR (OR = 1.67, 95% CI = 1.18-2.36, P = .004), PLR (OR = 1.03, 95% CI = 1.01-1.04, P = .001), and MPV (OR = 1.75, 95% CI = 1.15-2.66, P = .009) were independent risk factors for EOS. The AUC of the nomogram for the training set group was 0.872 (0.814, 0.931) and 0.889 (0.843, 0.935) in the validation set group. The P values of Hosmer-Lemeshow test for the training set and validation set groups were .903 and .752, respectively. The decision curve analyses outcome indicated good clinical practicability. The C-index for the training set and validation set groups were 0.872 and 0.889, respectively. The maternal NLR, PLR, and MPV levels had good predictive value for EOS in premature infants. The nomogram in our study could help clinicians predict the occurrence of EOS.
