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

research questionAre children born after assisted reproductive technology (ART) at higher risk of developing Langerhans cell histiocytosis (LCH)?

designRecords of children born after ART recorded by the UK Human Fertilisation & Embryology Authority were linked to National Registry of Childhood Tumours records to determine the number of children developing LCH. Calculated person-years at risk were used in conjunction with the incidence of LCH in the general population to determine the expected number of cases if the cohort had the same incidence as the general population with similar age and sex, over the same calendar years. The standardized incidence ratio (SIR) was derived as the ratio of observed to expected cases. Exact 95% CI were calculated.

resultsIn total, 118,155 children born after ART contributed 796,633 person-years follow-up (average follow-up 6.74 years). Eight cases of LCH were identified, compared with 3.75 cases expected (SIR 2.135, 95% CI 0.92-4.21; P = 0.074). Significantly more cases were associated with intracytoplasmic sperm injection (ICSI) (SIR 4.02, 95% CI 1.31-9.39) and male factor infertility (SIR 5.41, 95% CI 1.47-13.84). Most cases of LCH had single-system disease (n = 6).

conclusionsThis study found that significantly more cases of LCH were identified in children born after ICSI and in children whose parents had male factor infertility. A non-significant excess of cases in children born after ART was identified. Absolute excess risk was small. Given the rarity of LCH and the small number of cases included in this large cohort, further studies into the risk of LCH in children born after ART are indicated.
