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
aimsThis bioequivalence study aimed to compare rate and extent of absorption of a generic medicinal product of ibandronic acid 150-mg film-coated tablet versus Bonviva(®).
methodsThis was a single-centre, open-label, randomized, three-way, three-sequence, reference-replicated, crossover bioequivalence study, under fasting conditions. A single oral dose of ibandronic acid as one 150-mg film-coated tablet was administered in each study period. Each washout period lasted 14 days. Blood samples were collected according to a predefined sampling schedule and up to 48.0 hours after administraton in each period. Plasma concentrations of ibandronic acid were measured using a liquid chromatograph-mass spectrometry/mass spectrometry method. Bioequivalence between generic and reference medicinal products is acceptable if the 90 % confidence intervals (CI) of ratio of least-squares means between the test and the reference product of ln-transformed area under the serum concentration-time curve from time zero to time of last measurable concentration (AUC0-t ) is within the 80.00-125.00 % interval. Prospectively, a scaled average bioequivalence approach for maximum serum concentration (C max) was established.
results153 healthy volunteers were enrolled and randomized. After the test formulation (T) and first and second Bonviva(®) (R) dosing, the C max was 96.71 ± 90.19 ng/mL, 92.67 ± 91.48 ng/mL and 87.94 ± 60.20 ng/mL and the AUC0-t was 390.83 ± 287.27 ng·h/mL, 388.54 ± 356.76 ng·h/mL and 383.53 ± 246.72, respectively. Ratios of T/R and 90 % CI were 100.92 % (94.35-107.94) for AUC0-t , 100.90 % (94.37-107.88) for AUC0-inf and 102.56 % (95.05-110.67) for C max.
conclusionsTest formulation of ibandronic acid is bioequivalent in rate and extent of absorption to Bonviva(®) following a 150-mg dose, under fasting conditions.
