Short Communication: Association of Vitamin D Insufficiency and Protective Tenofovir Diphosphate Concentrations with Bone Toxicity in Adolescent Boys and Young Men Using Tenofovir Disoproxil Fumarate/Emtricitabine for HIV Pre-Exposure Prophylaxis.
Observational study in AIDS research and human retroviruses, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01769469 (Renal, Endocrine, and Bone Changes in Response to Treatment With Coformulated Emtricitabine-Tenofovir for Pre-Exposure HIV Prophylaxis), which is not on this map.

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
We examined associations of 25-hydroxy vitamin D (25-OHD), tenofovir disoproxil fumarate (TDF), and bone toxicity. We studied TDF/emtricitabine (FTC) HIV pre-exposure prophylaxis (PrEP) in young men who have sex with men (YMSM). Bone toxicity was predefined using bone mineral density/content change from baseline to week 48. Baseline serum 25-OHD was dichotomized as <20 ng/mL (insufficient/deficient) versus ≥20 (sufficient), and week 48 dried blood spot tenofovir diphosphate (TFV-DP) as >700 fmol/punch (protective against HIV acquisition) versus ≤700. Associations were examined by univariate and multivariable logistic regression, reporting crude and adjusted odds ratios (ORs), with 95% confidence intervals (CIs). Of 101 enrolled, 69 had complete bone assessments and 25-OHD; of these, 59 had week 48 TFV-DP data. Median (Q1-Q3) age was 20 (18-21) years; 54% were black/African American. In univariate analysis, participants with baseline 25-OHD <20 ng/mL (OR = 5.4; 95% CI = 1.9-16.5) and blacks (OR = 4.9; 95% CI = 1.7-15.2) had greater odds of bone toxicity than those with 25-OHD ≥20 or other races. TFV-DP was not associated with bone toxicity (OR = 1.6; 95% CI = 0.5-5.5). In multivariable analysis, compared with those with 25-OHD ≥20 and TFV-DP ≤700, those with 25-OHD ≥20 and TFV-DP >700 (OR = 11.5; 95% CI = 1.4-169.6), 25-OHD <20 and TFV-DP ≤700 (OR = 19.4; 95% CI = 3.0-228.7), and 25-OHD <20 and TFV-DP >700 (OR = 32.3; 95% CI = 3.3-653.6) had greater odds of bone toxicity after adjusting for race. In multivariable models, 25-OHD insufficiency, protective TFV-DP concentrations, and black race were significantly associated with bone toxicity after 48 weeks of TDF/FTC PrEP in YMSM.
