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

Ophthalmic sponges are used to collect undiluted cervical secretions for assessment of markers of genital tract immunity. Heterogeneity in absorbed and extracted sample volumes requires normalization in order to make valid inter-individual comparisons. We evaluated the performance of adjustment by weight and total protein on normalizing inter-individual variability of immune marker measurement due to differences in volume collection. Normalization to total protein resulted in a minimal loss of usable specimens and a significant reduction in the correlation of immune marker concentration to specimen weight compared to weight adjustment. Total protein normalization appeared to be more effective than weight adjustment in reducing the dependence of cervical immune marker concentrations on differences in specimen volume.
