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

Context: The association between blood parameters and gestational diabetes (GDM) is of renewed interest. Some blood cell parameters are assumed to be associated with GDM. Objective: This meta-analysis was performed to assess the association of hematological indices in the first trimester of pregnancy and later development of GDM. Methods: A comprehensive database search, including PubMed, Web of Science, Epistemonikos, Scopus, Scientific Information Database, and Magiran, was conducted to identify potential peer-reviewed publications. The PECO framework was applied to evaluate the eligibility of all included studies. Standardized mean differences (95% CI), were calculated. Additionally, pooled odds ratios, summary estimates of sensitivity and specificity, positive and negative likelihood ratios, and diagnostic odds ratios (DOR) were determined. Results: The meta-analysis encompassed 33 studies involving a total of 247 107 pregnant women. Compared to control groups, GDM groups exhibited statistically significantly higher hemoglobin levels (standard mean difference: 0.50, 95% CI: 0.39-0.62), red blood cell (RBC) (0.23, 0.15-0.32), and hematocrit (0.44, 0.34-0.55). The pooled adjusted estimate (aOR:1.02, 1.006-1.03) indicated that the hemoglobin levels were significantly associated with an increased risk of GDM. GDM groups had significantly higher platelet count (0.280, 0.16-0.39) and white blood cells (WBC) counts, as well as (0.482, 0.377-0.58), lymphocytes (0.12, 0.025-0.22), neutrophils (0.541:0.404-0.679), and neutrophil-lymphocyte ratio (0.31, 0.20-0.43). In distinguishing women with GDM from the control group, the DOR was found to be 3.21 for the hemoglobin and 2.94 for the mean platelet volume. Conclusion: Higher levels of RBC, platelet, and WBC counts during the first trimester of pregnancy were observed in women who subsequently developed GDM compared to control groups.
