Comparison of Paper Diaries, Text Messages and Smartphone App to Track Bleeding and Other Symptoms for Contraceptive Studies.
Trial report in Maternal and child health journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesMost researchers who study the effects of hormonal contraception on menstrual bleeding rely on self-reported data via paper diaries, for which completeness and timeliness have been shown to be poor. The purpose of this exploratory study was to compare the completeness and timeliness of bleeding data collected via paper diaries, text messages or smartphone application (a.k.a "app").
methodsThis was a sub-study of a double-blinded, placebo-controlled randomized trial comparing the effects of a non-steroidal anti-inflammatory drug, naproxen, with placebo when using a copper IUD. Participants tracked bleeding and symptoms over 112 days. Participants tracked bleeding daily using a paper diary as well as with either text messages or a smartphone app. Participants who used paper and the app were also able to record non-bleeding symptoms.
resultsTwenty-five participants submitted diaries. Of these participants, 10 completed both paper and app diaries, 7 completed both paper and text messages, 4 completed the paper diary only, 4 completed the app only. Text messages had the most complete data (108 days), followed by the app (96 days) and paper diaries (84 days). The lag time between a bleeding event and the date recording that event was 0.10 days for text, 1.0 days for app, and 4.73 days for paper diaries. Participants using the app reported a median of 33 other symptoms over the study period compared to 7 for the paper diaries. DISCUSSION: Our findings suggest texts demonstrated more complete and timely bleeding data than either paper diaries, or the app. Compared to paper diaries, the app delivered more complete, timely data, and also collected a large set of symptoms.
