Examining cultural background and the protective effect of marriage on alcohol use disorder in Sweden.

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
backgroundLittle is known about whether the protective effect of marriage on alcohol use disorder (AUD) varies by cultural background.
aimsUsing Swedish national data, we examined whether marriage is associated with a stronger reduction in AUD risk among Swedes of a Swedish background (i.e. those with two Swedish-born parents) compared to Swedes with a foreign background (i.e. one or two foreign-born parents) and whether the protective effect of marriage depends on whether the spouse has a Swedish or foreign background.
methodAmong those born in Sweden 1960 to 1990 (3,093,439; 49% female), associations between cultural background and AUD registration during marriage were estimated with Cox models. Analyses of intra- and intermarriage on AUD registration were examined with Cox models and limited to groups of focal individuals for which there was sufficient statistical power, which included Swedes with two Swedish-born parents, two Finnish-born parents, or bicultural background (one Swedish and one foreign-born parent). Models were sex stratified.
resultsMarriage was associated with reductions in AUD risk among those with Swedish and with foreign backgrounds, though less protective for males of Finnish versus Swedish background as indicated by a significant interaction between marital status and parental region of birth, HR = 0.80, 95% CI [0.71, 0.90]. Marriage was also less protective for those with a bicultural versus Swedish background, HR
conclusionsThe protective effect of marriage depends on cultural background, with some evidence that increased risks associated with a spouse's foreign background are confounded by family-level factors.
