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

backgroundThis study compared peripheral haematological inflammation indices obtained from complete blood count (CBC) parameters between preschoolers with developmental language disorder (DLD) and typically developing peers (TD) and examined the role of peripheral inflammatory processes in preschoolers with DLD.

methodsOne hundred twenty-seven children (61 with DLD and 66 TD) aged 36-60 months were included in this hospital-based, retrospective, case-controlled study. Complete blood count parameters and the resulting indices were compared: Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI). Statistical analyses included group comparisons, multivariable logistic regression, and Receiver Operating Characteristic (ROC) analysis.

resultsThe DLD registered significantly lower lymphocyte, higher monocyte, and NLR, SII and SIRI values compared to the TD (p = 0.015, p < 0.001, p < 0.001, p = 0.007, p < 0.001, respectively). Analysis of covariance revealed that the groups had a significant main effect on monocytes, NLR, SII and SIRI levels and that this effect was independent of age and gender. At multivariable logistic regression, SIRI emerged as a significant independent predictor of DLD, alongside male gender and a lower paternal education level ((p = 0.002, p = 0.007, p = 0.009, respectively). ROC analysis showed that SIRI had discriminative ability for DLD (AUC = 0.765, p < 0.001).

conclusionThe findings suggest that peripheral inflammatory processes, reflected by NLR, SII and particularly SIRI, may be associated with DLD in preschoolers. Although SIRI showed high specificity but low sensitivity, the present results provide preliminary evidence that it may represent a potential peripheral inflammation index associated with DLD.
