Weight and body composition changes during oral contraceptive use in obese and normal weight women.
Trial report in Journal of women's health (2002), 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05061472 (The Influence of Combined Oral Contraceptives on Weight, Body Composition, Eating Behaviors, and Appetite in Pre-menopausal Women With Overweight or Obesity), which is not on this map. Cited by 14 papers.
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.

Abstract
backgroundOral contraceptive (OC) use seems to have little effect on weight change in normal weight women. Most previous studies have excluded obese women, so the effect of OC use on weight change in obese women is unknown.
methodsThis analysis evaluates weight and body composition change with OC use among obese (body mass index [BMI] 30.0-39.9) and normal weight (BMI 19.0-24.9) women who were randomly assigned to two OC doses: 20 μg ethinyl estradiol (EE) and 100 μg levonorgestrel (LNG) OCs or 30 μg EE and 150 μg LNG OCs. Follow-up occurred after three to four OC cycles. Weight and body composition were measured at baseline and at follow-up using a bioelectrical impedance analyzer.
resultsAmong 150 women (54 obese and 96 normal weight) who used OCs for 3 to 4 months, there were no clinically or statistically significant weight or body composition changes in the overall group or by BMI or OC formulation group.
conclusionsThese findings add to evidence that EE/LNG OCs are not associated with short term weight or body composition change for normal weight women and suggest that OCs are also are not associated with short term weight or body composition change in obese women.
