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

objectiveTo investigate the prevalence of polycystic ovary syndrome (PCOS) in adolescents and its association with obesity.

designCross-sectional study using electronic medical records.

settingNot applicable. PATIENT(S): Adolescents aged 15-19 years (n = 137,502). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): PCOS diagnosed or defined according to National Institutes of Health (NIH) criteria. RESULT(S): The prevalence of a confirmed diagnosis of PCOS was 0.56%, which increased to 1.14% when undiagnosed cases with documented symptoms qualifying for PCOS according to NIH criteria were included. Compared with normal/underweight girls, the odds ratios (OR and 95% confidence interval [CI]) for confirmed PCOS diagnosis were 3.85 (3.04-4.88), 10.25 (8.16-12.84), and 23.10 (18.66-28.61) for overweight, moderately obese, and extremely obese adolescents, respectively, after adjusting for potential confounders. When adolescents with two or more supportive diagnoses were included (diagnosed and undiagnosed PCOS-NIH), the ORs (95% CI) for PCOS-NIH by weight class were significantly attenuated to 2.95 (2.53-3.44), 6.73 (5.78-7.83), and 14.65 (12.73-16.86) for overweight, moderately obese, and extremely obese adolescents, respectively. CONCLUSION(S): Overweight and obesity were associated with higher odds of PCOS in adolescents. Studies based solely on diagnosis codes may underestimate the prevalence of PCOS and overestimate the magnitude of the association between obesity and PCOS.
