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
introductionThere have been increasing concerns about the possible high prevalence of chronic kidney disease (CKD) among returnee Nepalese migrant workers from the Gulf countries and Malaysia. This population-based cross-sectional survey primarily aimed to examine the prevalence of kidney health risks of Nepalese recent migrants compared to non-migrants from the same community.
methodsWe conducted a cross-sectional survey of 1438 participants from Dhanusha district (718 recent migrants and 720 non-migrants (including historic migrants)). Recent migrants (all sexes) aged 18 years or above who had stayed for at least two years in six countries of the Gulf region or Malaysia in any occupation and had returned in the past 12 months were included. We used the core questionnaire and protocol for the Disadvantaged Populations eGFR Epidemiology Study (DEGREE) and added questions on migration.
resultsAll recent migrants were male and they were compared to male historic migrants, male non-migrants, and female non-migrants. Only 6 (0.4%) cases of eGFR < 60mL/min/1.73m2 were identified overall. The prevalences of eGFR < 60mL/min/1.73m2 were 0.4% (95% CI: 0.08 to 1.2), 0.5% (95% CI: 0.01 to 2.6), 1.2% (95% CI: 0.1 to 4.2%), and zero in male recent migrants, male historic migrants, male non-migrants, and female non-migrants, respectively. The prevalence of high proteinuria (> 30 mg/g) was lowest among male recent migrants at 7.7% (95% CI: 5.8 to 9.8) and highest among female non-migrants at 10.5% (95% CI: 7.5 to 14.3). In the adjusted multiple regression model, male recent migrants had a statistically nonsignificant, slightly reduced mean difference in eGFR of -0.8 mL/min/1.73m2 (95% CI: -3.6 to 2.0) compared to male non-migrants. A separate adjusted model among male recent migrants showed a strong association between reduced mean eGFR and older age, occupation as a security guard, current or past smokers, and ethnicity (Terai Dalits and Muslims).
conclusionThis study found a low prevalence of eGFR < 60mL/min/1.73m2 in Nepalese recent migrants. There were no associations of mean eGFR by migration status despite male migrants being exposed to risk factors for kidney disease. Nonetheless, this study indicated that specific sub-groups of Nepalese migrants mainly those working as security guards and from certain ethnicities could be at higher risk. These require further investigations.
