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

Oral contraceptive (OC)/low-dose estrogen progestin (LEP) affects both the coagulation and fibrinolytic systems and may cause alveolar osteitis (AO). However, whether OC/LEP discontinuation affects the incidence of AO has not been evaluated. The aim of this study was to investigate whether preoperative OC/LEP discontinuation influences the incidence of AO after wisdom tooth extraction in outpatients. A total of 130 women aged 18-47 years (median, 27 years) participated, and the total numbers of procedure days and teeth were 205 and 274, respectively. We compared the incidence of AOs between patients who discontinued OC/LEP before wisdom tooth extraction and those who did not. A total of 4/181 teeth (2.21%) in the discontinuation group and 7/93 (7.53%) in the continuation group exhibited AO, and Fisher's exact test revealed a significant difference between the two groups (
