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

purposeThe Daily Record of Severity of Problems (DRSP) is commonly used to assess premenstrual syndrome and premenstrual dysphoric disorder throughout the world. The aim of this study was to assess the validity and reliability of the Japanese version of the DRSP (DRSP-J). MATERIALS AND

methodsWe analyzed 324 women with regular menstrual cycles who completed the DRSP-J and the Premenstrual Symptoms Questionnaire (PSQ). They had all applied to participate in an ongoing study for the treatment of their premenstrual symptoms. The DRSP-J was examined for evidence of reliability and validity. To examine reliability, we assessed Cronbach's α, a measure of internal consistency, and test-retest reliability. We assessed structural validity with principal component factor analysis (PCA) and confirmatory factor analysis (CFA). We used PSQ total score to examine concurrent validity.

resultsCronbach's α for DRSP total score was 0.97. DRSP total score and individual items showed high test-retest reliability. PCA showed a two-factor model describing mood and behavioral and physical symptoms. CFA showed that the two-factor model derived from the PCA was an acceptably good fit. DRSP total score correlated moderately with PSQ total score (r = 0.42).

conclusionThe DRSP-J showed reliable and valid measures of premenstrual symptoms in Japanese women.
