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

backgroundHair loss on the central scalp commonly occurs among African American (AA) women and can pose substantial psychosocial burdens. The causes of hair loss remain obscure, although type 2 diabetes has been hypothesized to increase the risk of hair loss. The objective of the present study was to prospectively estimate the association between type 2 diabetes and severe central hair loss in AA women.

methodsThe Black Women's Health Study has collected data on medical and lifestyle factors, including diagnosis of type 2 diabetes, biennially since 1995 from AA women across the United States. The present analysis was based on responses from 5389 women to an online hair loss questionnaire in 2015. Respondents indicated severity of central hair loss on a validated six-item photographic scale; the highest levels, levels 3 to 5, were designated as severe. We used Cox proportional hazards models to estimate multivariable hazard ratios and 95% confidence intervals (CIs) for type 2 diabetes in relation to severe central hair loss.

resultsDuring the follow-up period, 850 cases of severe hair loss occurred. The multivariable hazard ratio for severe hair loss associated with diabetes was 1.68 (95% CI, 1.38-2.06) overall, and 2.05 (95% CI, 1.48-2.85) for diabetes duration of ≥ 10 years.

conclusionType 2 diabetes was associated with an increased risk of severe central scalp hair loss in AA women. Patients with type 2 diabetes should be followed closely for central scalp hair loss so that appropriate treatment can be offered.
