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

backgroundThe age of multiple sclerosis (MS) onset coincides with fertile age, and both improved prognosis and treatment may influence birth rates in people with MS (pwMS).

objectivesTo investigate birth rates over time in pwMS compared with controls.

methodsThis cohort study included pwMS from three hospitals in the southeast of Norway. Clinical data were collected prospectively. Statistics Norway provided year of live births and marital status in pwMS and controls matched for age, sex, and place of residence at age 16.

resultsWe included 1599 pwMS (1118 women with MS (wMS) and 481 men with MS (mMS)) and 23,855 controls. The mean number of live births was 1.5 (standard deviation (SD) 1.2) for pwMS versus 1.8 (SD 1.2) for controls (

conclusionwMS have reduced rates of childbirth compared with controls. This is significant already in the prodromal phase.
