1 · What the graph read from it

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.

2 · The registry

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

backgroundThe aim of this study was to evaluate the predictive value of the hematological parameters in the identification of human cytomegalovirus (CMV) infection in infants less than 3 months.

methodsA single-center, observational study of infants with CMV infection was conducted retrospectively. Routine blood parameters were analyzed in CMV-infected infants and controls with no differences of birthweight, sex, gestational age at birth, and date of admission. Furthermore, receiver-operating curve was used to assess the predictive value of the hematological parameters for CMV infection.

resultsOne hundred ninety cases with CMV infection were studied retrospectively. Compared with the control group, there were significant differences in the white blood cell count, neutrophil count, lymphocyte count, platelet count, hemoglobin, neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte (PLR), and lymphocyte-to-monocyte (LMR) for the patients with CMV infection (all p < 0.001). The best predicted values for CMV infection based on the area under the curve (AUC) were NLR and PLR with the optimal cut-off value of 0.28 and 65.36. NLR-PLR score of 0, 1, or 2 based on an elevated NLR (>0.28), an elevated PLR (>65.36), or both. NLR-PLR score for CMV infection prediction yielded higher AUC values than NLR or PLR alone (0.760 vs. 0.689, 0.689; p < 0.001).

conclusionsThe NLR combined with PLR is potentially useful as a predictor of CMV infection in infants less than 3 months.
