Diagnostic utility of haematological parameters for tuberculosis in children living with HIV (0-14 years): a retrospective cohort study.
Article in BMC pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundEarly detection of tuberculosis (TB) in children living with HIV (CLHIV) is crucial for improving clinical outcomes and reducing disease transmission. This study aimed to evaluate the association between hematological parameters, including the monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), and anemia status, and the presence of TB in CLHIV aged 0-14 years.
methodsThis retrospective cohort follow-up study included data from 276 CLHIV registered at the Antiretroviral Therapy (ART) Centre of a Tertiary Care Hospital in Gujarat, India, from January 2009 to March 2024. Demographic, clinical, and laboratory data were extracted from electronic medical records. Logistic regression models were developed to assess the predictive ability of hematological parameters for TB.
resultsAmong the study population, 56.9% had moderate anemia, and 11.2% had severe anemia. Children with TB had significantly lower mean hemoglobin levels, higher absolute neutrophil counts, and higher median MLR (0.460 ± 0.117 vs. 0.167 ± 0.143, p = 0.001) and NLR ratios (2.1 ± 0.3 vs. 1.7 ± 0.7, p = 0.001) compared to those without TB. Model 1 (MLR and anemia status) showed that individuals with a greater MLR ratio had 15.62 times higher adjusted odds of having TB (95% CI: 6.84-35.67, p < 0.001). Model 2 (NLR and anemia status) revealed that a high NLR ratio was associated with 17.28 times higher adjusted odds of TB (95% CI: 7.41-40.35, p < 0.001). Model 3 (MLR, NLR, and anemia status) demonstrated the best predictive ability (AUC = 0.892, accuracy = 88%, sensitivity = 94.2%).
conclusionHigher MLR and NLR ratios were associated with increased odds of having TB in CLHIV. The combination of these hematological parameters, along with anemia status, exhibited promising predictive ability for TB in this population. These findings highlight the potential utility of routinely available hematological parameters in predicting TB disease in CLHIV.
