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

Purpose: To evaluate the prognostic potential of systemic inflammatory index in the course of retinopathy of prematurity (ROP). Methods: This is a retrospective case-control study. 303 infants with a gestational age of ≤35 weeks were screened with and without ROP at birth and 1 month after the birth of complete blood counts (CBC) were included in this study. Serum neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), platelet-to-lymphocyte (PLR), and systemic immune-inflammation index (SII) was calculated at birth and one month after. LMR was calculated by dividing the absolute lymphocyte count by the absolute monocyte count. NLR and PLR were determined by dividing the absolute neutrophil count or the absolute platelet count by the absolute lymphocyte count, respectively. The SII was calculated by the formula = neutrophilxplatelet/lymphocyte. All statistical analyses were performed using SPSS 22 (SPSS for Windows, version 22.0; SPSS, Inc. Chicago, IL, USA). Results: A total of 303 infants were included 145 with ROP and 158 without ROP. The NLR, LMR, PLR and SII values were 0.56 ± 1.17/0.51 ± 1.04 (P = 0.997), 13.7 ± 18/9.49 ± 13.1 (P = 0.014), 31.69 ± 68/24.1 ± 37.7 (P = 0.268), 131.42 ± 326/124.66 ± 267 (P = 0.935) in with ROP and without ROP infant at birth respectively. The NLR, LMR, PLR, and SII values were 0.68 ± 1.27/0.34 ± 0.99 (P = 0.001), 2.58 ± 6.01/2.46 ± 14.5 (P = 0.706), 47.5 ± 78.33/33.55 ± 42.4 (P = 0.035), and 253 ± 681/114 ± 345 (P = 0.001), respectively in with ROP and without ROP infant at 1 month after birth. Conclusion: The NLR, PLR, and SII seem an independent predictor of the development of ROP.
