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.
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
objectivesHormonal changes during pregnancy can increase susceptibility to plaque-induced gingivitis, and at the same time, dental care visits during pregnancy have been reported to be low. This study evaluated the effect of an oral health education program on knowledge, attitude, and clinical indices of oral health in pregnant women.
methodsThis nonrandomized controlled intervention study was conducted at Kowsar Hospital, Urmia. Allocation to groups was based on the day of visit (even/odd days). In addition to routine prenatal care, the intervention group received an individual education session of approximately 60 min with a brochure, and the control group received routine care only. Knowledge, attitude, plaque index (PI), gingival index (GI), and decayed, missing, and filled teeth (DMFT) indices were measured at baseline and 3 months later. Statistical analysis was performed in Statistical Package for the Social Sciences.
resultsOf 240 enrolled participants, 200 (100 per group) provided complete follow-up data. Baseline characteristics and oral health indices were comparable between groups. At 3 months, the intervention group demonstrated improved knowledge and attitude, lower PI, and modest improvement in GI. In the control group, knowledge and attitude changed little, GI worsened, and PI remained largely unchanged. DMFT increased in both groups over the 3-month period.
conclusionsShort-term, structured oral health education with a brochure can improve knowledge and attitude of pregnant women in the short term and improve plaque and gingivitis.
