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
objectiveThis research compares the effectiveness of three whitening treatments for mild-to-moderate dental fluorosis in the front teeth.
methodThis retrospective study analysis is based on 51 mild-to-moderate dental fluorosis cases. The patients who visited the Dental Hospital of Ningxia Medical University from August 2020 to August 2021 were enrolled as research cases. The patients were classified into three groups according to their treatment plans: Group A (19 cases), Group B (17 cases), and Group C (15 cases). The upper anterior teeth color was assessed immediately after treatment and then at one week, one month, three months, and six months using the VITA Easyshade
resultsThree options were applied to treat mild and moderate dental fluorosis. Moderate fluorosis showed higher ΔE and ΔL values but lower Δa and Δb values compared to mild fluorosis, with significant differences noted (P<0.05). In cases of mild dental fluorosis, ΔE and ΔL values from the combination of micro-grinding and home bleaching were significantly higher. Conversely, Δa and Δb values for both micro-grinding with home bleaching and micro-grinding with combined bleaching were significantly lower (P<0.05). In moderate dental fluorosis cases, ΔE and ΔL values were higher for both micro-grinding combined with bleaching and micro-grinding combined with home bleaching. In contrast, Δa and Δb values for micro-grinding combined with bleaching were lower, showing statistically significant differences (P<0.05). The sensitivity of micro-grinding + home bleaching was less than that of micro-grinding + in-office bleaching and micro-grinding + combined bleaching immediately post-op, 1 week after the operation, with statistically significant differences (P<0.05).
conclusionAll three options achieve sound whitening effects for mild to moderate dental fluorosis in anterior teeth. The whitening effect is more effective in cases of moderate dental fluorosis than in mild cases. Among the three treatment options, microabrasion combined with home bleaching achieves the best whitening effect for mild dental fluorosis and minimizes sensitivity. When considering the three treatment options for moderate dental fluorosis, both microabrasion combined with home bleaching and microabrasion combined with in-office bleaching can yield better whitening effects. However, it is essential to note that the latter option is linked to higher sensitivity.
