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

Background and objectives Existing studies have primarily focused on autoimmune thyroid disorders in patients with chronic spontaneous urticaria (CSU); fewer studies have assessed thyroid function using routine thyroid function tests alone. The purpose of this study was to estimate the prevalence and pattern of common thyroid disorders among CSU patients at a tertiary care center. Methods A descriptive cross-sectional study was conducted among 123 patients aged above 18 years with CSU visiting the Urticaria OPD at Rajiv Gandhi Government General Hospital. After obtaining written informed consent, patients were assessed using a validated, interviewer-administered questionnaire and examined clinically. All patients underwent serum thyroid function testing, including free T3, free T4, and thyroid-stimulating hormone estimation by chemiluminescence Immunoassay. Data were entered into Microsoft Excel and analyzed using IBM SPSS Statistics for Windows, Version 26 (Released 2018; IBM Corp., Armonk, New York, United States) to determine the prevalence and pattern of thyroid disorders among CSU patients. Chi-square, Fisher's exact test, Mann-Whitney U test, and odds ratios with 95% confidence intervals were used for inferential analysis. Results The prevalence of thyroid abnormalities among patients with CSU was 29 of 123 patients (23.5%; 95% CI: 16.9-31.8%). Hypothyroidism was observed in 28 (22.8%) patients and constituted the majority of abnormalities, while hyperthyroidism was observed in one patient (0.8%). Thyroid dysfunction was observed in 16 (28.0%) patients aged <45 years and 13 (19.6%) patients aged ≥45 years (p=0.339). Female patients showed higher rates of thyroid dysfunction (27.1%) compared to male patients (15.8%), though this difference was not statistically significant (p=0.174). Conclusion The relatively high prevalence of thyroid dysfunction observed in this cohort suggests that thyroid function assessment may be considered in selected CSU patients, particularly where clinical suspicion exists.
